I never saw the Prophet ﷺ seeking to fast on a day that he favored more than another except this day, the day of 'Ashura', and this month, meaning the month of Ramadan.  

مَا رَأَيْتُ النَّبِيَّ ﷺ يَتَحَرَّى صِيَامَ يَوْمٍ فَضَّلَهُ عَلَى غَيْرِهِ إِلاَّ هَذَا الْيَوْمَ يَوْمَ عَاشُورَاءَ وَهَذَا الشَّهْرَ يَعْنِي شَهْرَ رَمَضَانَ  

The Prophet ﷺ said, "Time has taken its original shape which it had when Allah created the Heavens and the Earth. The year is of twelve months, four of which are sacred, and out of these (four) three are in succession, i.e. Dhul-Qa'da, Dhul-Hijja and Al-Muharram, and the fourth is Rajab which is named after the Mudar tribe, between (the month of) Jumaida (ath-thania) and Sha'ban." Then the Prophet ﷺ asked, "Which is this month?" We said, "Allah and His Apostle know better." On that the Prophet ﷺ kept quiet so long that we thought that he might name it with another name. Then the Prophet ﷺ said, "Isn't it the month of Dhul-Hijja?" We replied, "Yes." Then he said, "Which town is this?" "We replied, "Allah and His Apostle know better." On that he kept quiet so long that we thought that he might name it with another name. Then he said, "Isn't it the town of Mecca?" We replied, "Yes, " Then he said, "Which day is today?" We replied, "Allah and His Apostle know better." He kept quiet so long that we thought that he might name it with another name. Then he said, "Isn't it the day of An- Nahr (i.e. sacrifice)?" We replied, "Yes." He said, "So your blood, your properties, (The sub-narrator Muhammad said, 'I think the Prophet ﷺ also said: And your honor..) are sacred to one another like the sanctity of this day of yours, in this city of yours, in this month of yours; and surely, you will meet your Lord, and He will ask you about your deeds. Beware! Do not become infidels after me, cutting the throats of one another. It is incumbent on those who are present to convey this message (of mine) to those who are absent. May be that some of those to whom it will be conveyed will understand it better than those who have actually heard it." (The sub-narrator, Muhammad, on remembering that narration, used to say, "Muhammad spoke the truth!") He (i.e. Prophet) then added twice, "No doubt! Haven't I conveyed (Allah's Message) to you?"  

عَنِ النَّبِيِّ ﷺ قَالَ الزَّمَانُ قَدِ اسْتَدَارَ كَهَيْئَةِ يَوْمَ خَلَقَ السَّمَوَاتِ وَالأَرْضَ السَّنَةُ اثْنَا عَشَرَ شَهْرًا مِنْهَا أَرْبَعَةٌ حُرُمٌ ثَلاَثَةٌ مُتَوَالِيَاتٌ ذُو الْقَعْدَةِ وَذُو الْحِجَّةِ وَالْمُحَرَّمُ وَرَجَبُ مُضَرَ الَّذِي بَيْنَ جُمَادَى وَشَعْبَانَ أَىُّ شَهْرٍ هَذَا قُلْنَا اللَّهُ وَرَسُولُهُ أَعْلَمُ فَسَكَتَ حَتَّى ظَنَنَّا أَنَّهُ سَيُسَمِّيهِ بِغَيْرِ اسْمِهِ قَالَ أَلَيْسَ ذُو الْحِجَّةِ قُلْنَا بَلَى قَالَ فَأَىُّ بَلَدٍ هَذَا قُلْنَا اللَّهُ وَرَسُولُهُ أَعْلَمُ فَسَكَتَ حَتَّى ظَنَنَّا أَنَّهُ سَيُسَمِّيهِ بِغَيْرِ اسْمِهِ قَالَ أَلَيْسَ الْبَلْدَةَ قُلْنَا بَلَى قَالَ فَأَىُّ يَوْمٍ هَذَا قُلْنَا اللَّهُ وَرَسُولُهُ أَعْلَمُ فَسَكَتَ حَتَّى ظَنَنَّا أَنَّهُ سَيُسَمِّيهِ بِغَيْرِ اسْمِهِ قَالَ أَلَيْسَ يَوْمَ النَّحْرِ قُلْنَا بَلَى قَالَ فَإِنَّ دِمَاءَكُمْ وَأَمْوَالَكُمْ قَالَ مُحَمَّدٌ وَأَحْسِبُهُ قَالَ وَأَعْرَاضَكُمْ عَلَيْكُمْ حَرَامٌ كَحُرْمَةِ يَوْمِكُمْ هَذَا فِي بَلَدِكُمْ هَذَا فِي شَهْرِكُمْ هَذَا وَسَتَلْقَوْنَ رَبَّكُمْ فَسَيَسْأَلُكُمْ عَنْ أَعْمَالِكُمْ أَلاَ فَلاَ تَرْجِعُوا بَعْدِي ضُلاَّلاً يَضْرِبُ بَعْضُكُمْ رِقَابَ بَعْضٍ أَلاَ لِيُبَلِّغِ الشَّاهِدُ الْغَائِبَ فَلَعَلَّ بَعْضَ مَنْ يُبَلَّغُهُ أَنْ يَكُونَ أَوْعَى لَهُ مِنْ بَعْضِ مَنْ سَمِعَهُ فَكَانَ مُحَمَّدٌ إِذَا ذَكَرَهُ يَقُولُ صَدَقَ مُحَمَّدٌ ﷺ ثُمَّ قَالَ أَلاَ هَلْ بَلَّغْتُ مَرَّتَيْنِ  

he attributed this to the Prophet ﷺ: He was asked which prayer is best after the obligatory prayers and which fasting is best after the month of Ramadan? He said: (1) The best prayer after the obligatory prayers is the one offered in the middle of the night, and (2) the best fast after the month of Ramadan is the fast in the Month of Allah: al-Muharram.  

سُئِلَ أَىُّ الصَّلاَةِ أَفْضَلُ بَعْدَ الْمَكْتُوبَةِ وَأَىُّ الصِّيَامِ أَفْضَلُ بَعْدَ شَهْرِ رَمَضَانَ فَقَالَ أَفْضَلُ الصَّلاَةِ بَعْدَ الصَّلاَةِ الْمَكْتُوبَةِ الصَّلاَةُ فِي جَوْفِ اللَّيْلِ وَأَفْضَلُ الصِّيَامِ بَعْدَ شَهْرِ رَمَضَانَ صِيَامُ شَهْرِ اللَّهِ الْمُحَرَّمِ  

When the Prophet ﷺ on the day of 'Ashurah and commanded us to fast on it, they (i.e. Companions) said: Messenger of Allah, this is a day which is considered great by Jews and Christians ? The Messenger of Allah ﷺ said: When the next year comes, we shall fast on the 9th of Muharram. But the next year the Messenger of Allah ﷺ breathed his last.  

سَمِعْتُ عَبْدَ اللَّهِ بْنَ عَبَّاسٍ يَقُولُ حِينَ صَامَ النَّبِيُّ ﷺ يَوْمَ عَاشُورَاءَ وَأَمَرَنَا بِصِيَامِهِ قَالُوا يَا رَسُولَ اللَّهِ إِنَّهُ يَوْمٌ تُعَظِّمُهُ الْيَهُودُ وَالنَّصَارَى فَقَالَ رَسُولُ اللَّهِ ﷺ فَإِذَا كَانَ الْعَامُ الْمُقْبِلُ صُمْنَا يَوْمَ التَّاسِعِ فَلَمْ يَأْتِ الْعَامُ الْمُقْبِلُ حَتَّى تُوُفِّيَ رَسُولُ اللَّهِ ﷺ  

He (al-Bāhilī) came to the Messenger of Allah ﷺ, then went away and came back to him after a year, and his condition and appearance had changed. He said, “O Messenger of Allah, do you not recognize me?” He said, “Who are you?” He said, “I am the al-Bāhilī who came to you last year.” He said, “What has changed you, when you used to be of good appearance?” He said, “I have not eaten any food except at night since I left you.” The Messenger of Allah ﷺ said, “Why have you tortured yourself?”

Then he said, “Fast the month of patience (i.e. Ramaḍān), and one day from every month.” He said, “Increase it for me, for I have strength.” He said, “Fast two days.” He said, “Increase it for me.” He said, “Fast three days.” He said, “Increase it for me.” He said, “Fast during the sacred months and leave off; fast during the sacred months and leave off; fast during the sacred months and leave off.” And he gestured with his three fingers, drawing them together and then releasing them.  

أَنَّهُ أَتَى رَسُولَ اللَّهِ ﷺ ثُمَّ انْطَلَقَ فَأَتَاهُ بَعْدَ سَنَةٍ وَقَدْ تَغَيَّرَتْ حَالَتُهُ وَهَيْئَتُهُ فَقَالَ: يَا رَسُولَ اللَّهِ أَمَا تَعْرِفُنِي؟ قَالَ: «وَمَنْ أَنْتَ؟» قَالَ: أَنَا الْبَاهِلِيُّ الَّذِي جِئْتُكَ عَامَ الأَوَّلِ۔ قَالَ: «فَمَا غَيَّرَكَ وَقَدْ كُنْتَ حَسَنَ الْهَيْئَةِ؟» قَالَ: مَا أَكَلْتُ طَعَامًا إِلاَّ بِلَيْلٍ مُنْذُ فَارَقْتُكَ۔ فَقَالَ رَسُولُ اللَّهِ ﷺ: «لِمَ عَذَّبْتَ نَفْسَكَ؟»

ثُمَّ قَالَ: «صُمْ شَهْرَ الصَّبْرِ، وَيَوْمًا مِنْ كُلِّ شَهْرٍ۔» قَالَ: زِدْنِي فَإِنَّ بِي قُوَّةً۔ قَالَ: «صُمْ يَوْمَيْنِ۔» قَالَ: زِدْنِي۔ قَالَ: «صُمْ ثَلاَثَةَ أَيَّامٍ۔» قَالَ: زِدْنِي۔ قَالَ: «صُمْ مِنَ الْحُرُمِ وَاتْرُكْ، صُمْ مِنَ الْحُرُمِ وَاتْرُكْ، صُمْ مِنَ الْحُرُمِ وَاتْرُكْ۔» وَقَالَ بِأَصَابِعِهِ الثَّلاَثَةِ فَضَمَّهَا ثُمَّ أَرْسَلَهَا  

“I came to the Prophet ﷺ and said: ‘O Prophet of Allah, I am the man who came to you last year.’ He said: ‘Why do I see your body so thin (and weak)?’ He said: ‘O Messenger of Allah! I do not eat during the day; I only eat at night.’ He said: ‘Who commanded you to punish yourself?’ I said: ‘O Messenger of Allah! I am strong enough.’ He said: ‘Fast the month of patience* and one day after it.’ I said: ‘I am strong enough (to do more).’ He said: ‘Fast the month of patience and two days after it.’ I said: ‘I am strong enough (to do more).’ He said: ‘Fast the month of patience and three days after it, and fast the sacred months.’”  

أَتَيْتُ النَّبِيَّ ﷺ فَقُلْتُ يَا نَبِيَّ اللَّهِ أَنَا الرَّجُلُ الَّذِي أَتَيْتُكَ عَامَ الأَوَّلِ قَالَ فَمَا لِي أَرَى جِسْمَكَ نَاحِلاً قَالَ يَا رَسُولَ اللَّهِ مَا أَكَلْتُ طَعَامًا بِالنَّهَارِ مَا أَكَلْتُهُ إِلاَّ بِاللَّيْلِ قَالَ مَنْ أَمَرَكَ أَنْ تُعَذِّبَ نَفْسَكَ قُلْتُ يَا رَسُولَ اللَّهِ إِنِّي أَقْوَى قَالَ صُمْ شَهْرَ الصَّبْرِ وَيَوْمًا بَعْدَهُ قُلْتُ إِنِّي أَقْوَى قَالَ صُمْ شَهْرَ الصَّبْرِ وَيَوْمَيْنِ بَعْدَهُ قُلْتُ إِنِّي أَقْوَى قَالَ صُمْ شَهْرَ الصَّبْرِ وَثَلاَثَةَ أَيَّامٍ بَعْدَهُ وَصُمْ أَشْهُرَ الْحُرُمِ  

[Machine] I came to the Messenger of Allah ﷺ once for a need. He said, “Who are you?” I said, “Do you not recognize me?” He said, “And who are you?” I said, “I am the Bahili who came to you last year.” He said, “You came to me with a fine body, complexion, and appearance—so what has brought you to what I see?” I said, “By Allah, since I left you I have not broken my fast except at night.” He said, “Who commanded you to torture yourself?”—three times. “Fast the month of patience: Ramadan.” I said, “I find strength, and I would like you to increase me.” He said, “Then fast one day of the month.” I said, “I find strength, and I would like you to increase me.” He said, “Then two days of the month.” I said, “I find strength, and I would like you to increase me.” He said, “What more do you seek beyond the month of patience and two days in the month?” I said, “I find strength, and I would like you to increase me.” He said, “Then three days of the month.” And he pressed him at the third time, and he could hardly speak. I said, “I find strength, and I would like you to increase me.” He said, “Then fast in the sacred months, and break your fast.”  

أَتَيْتُ رَسُولَ اللهِ ﷺ لِحَاجَةٍ مَرَّةً فَقَالَ مَنْ أَنْتَ؟ قَالَ أَوَ مَا تَعْرِفُنِي؟ قَالَ وَمَنْ أَنْتَ؟ قَالَ أَنَا الْبَاهِلِيُّ الَّذِي أَتَيْتُكَ عَامَ أَوَّلٍ قَالَ فَإِنَّكَ أَتَيْتَنِي وَجِسْمُكَ وَلَوْنُكَ وَهَيْئَتُكَ حَسَنَةٌ فَمَا بَلَغَ بِكَ مَا أَرَى؟ فَقَالَ إِنِّي وَاللهِ مَا أَفْطَرْتُ بَعْدَكَ إِلَّا لَيْلًا قَالَ مَنْ أَمَرَكَ أَنْ تُعَذِّبَ نَفْسَكَ؟ ثَلَاثَ مَرَّاتٍ صُمْ شَهْرَ الصَّبْرِ رَمَضَانَ قُلْتُ إِنِّي أَجِدُ قُوَّةً وَإِنِّي أُحِبُّ أَنْ تَزِيدَنِي قَالَ فَصُمْ يَوْمًا مِنَ الشَّهْرِ قُلْتُ إِنِّي أَجِدُ قُوَّةً وَإِنِّي أُحِبُّ أَنْ تَزِيدَنِي قَالَ فَيَوْمَيْنِ مِنَ الشَّهْرِ قُلْتُ إِنِّي أَجِدُ قُوَّةً وَإِنِّي أُحِبُّ أَنْ تَزِيدَنِي قَالَ وَمَا تَبْغِي عَنْ شَهْرِ الصَّبْرِ وَيَوْمَيْنِ فِي الشَّهْرِ قَالَ قُلْتُ إِنِّي أَجِدُ قُوَّةً وَإِنِّي أُحِبُّ أَنْ تَزِيدَنِي قَالَ فَثَلَاثَةَ أَيَّامٍ مِنَ الشَّهْرِ قَالَ وَأَلْحَمَ عِنْدَ الثَّالِثَةِ فَمَا كَادَ قُلْتُ إِنِّي أَجِدُ قُوَّةً وَإِنِّي أُحِبُّ أَنْ تَزِيدَنِي قَالَ فَمِنَ الْحُرُمِ وَأَفْطِرْ  

The father or Uncle of Mujibah al-Bahiliyyah visited the Messenger of Allah ﷺ. He then went away and came to him (again) after one year when his condition and appearance had changed. He said: Messenger of Allah, do you not recognize me? He asked: Who are you? He replied: I am al-Bahili who came to you last year. He said: What has changed you? You were looking well, then you were good in appearance? He said: I have only food at night since I departed from you. Thereupon the Messenger of Allah ﷺ said: Why did you torment yourself? Fast during Ramadan (the month of patience) and fast for one day every month. He said: Increase it for me, for I have (more) strength. He said: Fast two days. He again said: Increase it for me. He said: Fast three days. He again said: Increase it for me. He said: Fast during the inviolable months and then stop; fast during the inviolable months and then stop; fast during the inviolable months and then stop. He indicated by his three fingers, and joined them and then opened them. (Using translation from Abū Dāʾūd 2428)   

أَنَّهُ أَتَى رَسُولَ اللهِ ﷺ ثُمَّ انْطَلَقَ فَعَادَ إِلَيْهِ بَعْدَ سَنَةٍ وَفِي رِوَايَةِ أَبِي مُوسَى فَأَتَاهُ بَعْدَ سَنَةٍ وَقَدْ تَغَيَّرَتْ حَالُهُ وَهَيْئَتُهُ فَقَالَ يَا رَسُولَ اللهِ أَمَا تَعْرِفُنِي؟ قَالَ وَمَنْ أَنْتَ؟ قَالَ أَنَا الْبَاهِلِيُّ الَّذِي جِئْتُكَ عَامَ أَوَّلَ قَالَ فَمَا غَيَّرَكَ وَقَدْ كُنْتَ حَسَنَ الْهَيْئَةِ قَالَ مَا أَكَلْتُ طَعَامًا مُنْذُ فَارَقْتُكَ إِلَّا بِلَيْلٍ فَقَالَ رَسُولُ اللهِ ﷺ لِمَ عَذَّبْتَ نَفْسَكَ صُمْ شَهْرَ الصَّبْرِ وَمِنْ كُلِّ شَهْرٍ يَوْمًا قَالَ زِدْنِي فَإِنَّ بِي قُوَّةً قَالَ صُمْ مِنْ كُلِّ شَهْرٍ يَوْمَيْنِ قَالَ زِدْنِي فَإِنَّ بِي قُوَّةً قَالَ صُمْ ثَلَاثَةَ أَيَّامٍ زَادَ عَبْدُ الْوَاحِدِ مِنْ كُلِّ شَهْرٍ قَالَ زِدْنِي فَإِنَّ بِي قُوَّةً قَالَ صُمْ مِنَ الْحُرُمِ وَاتْرُكْ يَقُولُهَا ثَلَاثًا وَفِي رِوَايَةِ مُوسَى قَالَ زِدْنِي قَالَ صُمْ مِنَ الْحُرُمِ وَاتْرُكْ صُمْ مِنَ الْحُرُمِ وَاتْرُكْ صُمْ مِنَ الْحُرُمِ وَاتْرُكْ وَقَالَ بِأَصَابِعِهِ الثَّلَاثِ فَضَمَّهَا ثُمَّ أَرْسَلَهَا  

the Messenger of Allah said: "The most virtuous fasting after the month of Ramadan is Allah's month Al-Muharram."  

قَالَ رَسُولُ اللَّهِ ﷺ أَفْضَلُ الصِّيَامِ بَعْدَ صِيَامِ شَهْرِ رَمَضَانَ شَهْرُ اللَّهِ الْمُحَرَّمُ  

[Machine] The Prophet ﷺ crossed paths with some people from the Jews who were fasting on the day of Ashura. He asked, "What is the significance of this fasting?" They replied, "This is the day on which Allah saved Moses and the Children of Israel from drowning, and drowned Pharaoh. On this day, the ark also came to rest on Mount Judi, so Noah and Moses fasted in gratitude to Allah." Upon hearing this, the Prophet ﷺ said, "I have a greater right to Moses than they do, and this fasting is more deserving for me." He then commanded his companions to observe the fast.  

مَرَّ النَّبِيُّ ﷺ بِأُنَاسٍ مِنَ الْيَهُودِ قَدْ صَامُوا يَوْمَ عَاشُورَاءَ فَقَالَ مَا هَذَا مِنَ الصَّوْمِ؟ قَالُوا هَذَا الْيَوْمُ الَّذِي نَجَّى اللهُ مُوسَى وَبَنِي إِسْرَائِيلَ مِنَ الْغَرَقِ وَغَرَّقَ فِيهِ فِرْعَوْنَ وَهَذَا يَوْمُ اسْتَوَتْ فِيهِ السَّفِينَةُ عَلَى الْجُودِيِّ فَصَامَ نُوحٌ وَمُوسَى شُكْرًا لِلَّهِ فَقَالَ النَّبِيُّ ﷺ أَنَا أَحَقُّ بِمُوسَى وَأَحَقُّ بِصَوْمِ هَذَا الْيَوْمِ فَأَمَرَ أَصْحَابَهُ بِالصَّوْمِ  

[Machine] "That the Messenger of Allah ﷺ said: 'If I live until the next year, I will certainly fast the ninth day (of Muharram),' meaning the day of Ashura."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ لَئِنْ عِشْتُ قَالَ رَوْحٌ لَئِنْ سَلِمْتُ إِلَى قَابِلٍ لَأَصُومَنَّ الْيَوْمَ التَّاسِعَ يَعْنِي عَاشُورَاءَ  

[Machine] The Messenger of Allah ﷺ said: "Fast on the day of Ashura and be different from the Jews. Fast a day before it or a day after it."  

قَالَ رَسُولُ اللهِ ﷺ صُومُوا يَوْمَ عَاشُورَاءَ وَخَالِفُوا فِيهِ الْيَهُودَ صُومُوا قَبْلَهُ يَوْمًا أَوْ بَعْدَهُ يَوْمًا  

[Machine] The Messenger of Allah ﷺ said: "Rajab is a great month in which Allah multiplies the rewards. So whoever fasts for a day in Rajab, it is as if he has fasted for a whole year. And whoever fasts for seven days, the seven gates of Hell will be closed to him. And whoever fasts for eight days, the eight gates of Paradise will be opened for him. And whoever fasts for ten days, Allah will grant him whatever he asks for. And whoever fasts for fifteen days, a caller will announce in the heavens: 'May Allah forgive what has passed for you, so start anew.' And whoever does more, Allah will increase it. And in Rajab, Allah carried Noah in the ark, so he fasted in Rajab and commanded his companions to fast. The ark set sail with them for six months, until they landed on Mount Judi. And Noah and those with him expressed gratitude to Allah. And on the day of Ashura, Allah split the sea for the children of Israel. And on the day of Ashura, Allah accepted the repentance of Adam and the city of Yunus. And in Rajab, Ibrahim ﷺ was born."  

قَالَ رَسُولُ اللهِ ﷺ «رَجَبٌ شَهْرٌ عَظِيمٌ يُضَاعِفُ اللهُ فِيهِ الْحَسَنَاتِ فَمَنْ صَامَ يَوْمًا مِنْ رَجَبٍ فَكَأَنَّمَا صَامَ سَنَةً وَمَنْ صَامَ مِنْهُ سَبْعَةَ أَيَّامٍ غُلِّقَتْ عَنْهُ سَبْعَةُ أَبْوَابِ جَهَنَّمَ وَمَنْ صَامَ مِنْهُ ثَمَانِيَةَ أَيَّامٍ فُتِحَتْ لَهُ ثَمَانِيَةُ أَبْوَابِ الْجَنَّةِ وَمَنْ صَامَ مِنْهُ عَشَرَةَ أَيَّامٍ لَمْ يَسْأَلِ اللهَ شَيْئًا إِلَّا أَعْطَاهُ إِيَّاهُ وَمَنْ صَامَ مِنْهُ خَمْسَةَ عَشَرَ يَوْمًا نَادَى مُنَادٍ فِي السَّمَاءِ قَدْ غُفِرَ لَكَ مَا مَضَى فَاسْتَئْنِفِ الْعَمَلَ وَمَنْ زَادَ زَادَهُ اللهُ ﷻ وَفِي رَجَبٍ حَمَلَ اللهُ نُوحًا فِي السَّفِينَةِ فَصَامَ رَجَبًا وَأَمَرَ مَنْ مَعَهُ أَنْ يَصُومُوا فَجَرَتْ بِهِمُ السَّفِينَةُ سِتَّةَ أَشْهُرٍ آخِرُ ذَلِكَ يَوْمُ عَاشُورَاءَ أُهْبِطَ عَلَى الْجُودِيِّ فَصَامَ نُوحٌ وَمَنْ مَعَهُ وَالْوَحْشُ شُكْرًا لِلَّهِ ﷻ وَفِي يَوْمِ عَاشُورَاءَ أفْلَقَ اللهُ الْبَحْرَ لِبَنِي إِسْرَائِيلَ وَفِي يَوْمِ عَاشُورَاءَ تَابَ اللهُ ﷻ عَلَى آدَمَ ﷺ وَعَلَى مَدِينَةِ يُونُسَ وَفِيهِ وُلِدَ إِبْرَاهِيمُ ﷺ»  

[Machine] Whoever fasts one day in Rajab, it is like fasting for a year. Whoever fasts seven days, the seven gates of Hell are shut against him. Whoever fasts eight days, the eight gates of Paradise are opened for him. Whoever fasts ten days, he does not ask God for anything except that He grants it to him. Whoever fasts fifteen days, a caller from heaven proclaims: “I have forgiven you what has passed, so begin your deeds anew; I have replaced your bad deeds with good deeds.” And whoever does more, God increases for him.

And in Rajab, Noah was carried in the Ark, and Noah fasted and commanded those with him to fast; and the Ark carried them for six months, until the end of that, on the tenth day of Muharram.  

"مَنْ صَامَ يَوْمًا مِنْ رَجَبٍ كانَ كَصِيَامِ سَنَة، وَمَن صَامَ سَبْعَةَ أَيَّامٍ غُلِّقَتْ عَنْهُ سَبْعَةُ أَبْوَاب جَهَنَّمَ، وَمَن صَامَ ثَمَانِيَةَ أَيَّامٍ فُتِّحَتْ لَهُ ثَمَانِيَةُ أَبْوَابِ الجَنَّةِ، وَمَنْ صَامَ عَشْرَةَ أَيَّامٍ لَمْ يَسْألِ اللهَ شَيئًا إِلا أَعْطَاهُ، وَمَن صَامَ خَمْسَةَ عَشَرَ يَوْمًا نَادَى مُنَادٍ مِنَ السَّمَاءِ: قَدْ غَفَرْتُ لَكَ مَا سَلَفَ، فَاسْتَأنِف العَمَلَ، قَدْ بَدَّلتُ سيئاتِكَ حَسَنَات، وَمَن زَادَ زَادَهُ اللهُ، وفِي رَجَبٍ حُمِلَ نُوح بِالسَّفِينة وَصَامَ نُوحٌ وَأَمَرَ مَنْ مَعَهُ أَنْ يَصُومُوا، وَجَرَت بِهِم السفِينَةُ سِتَّةَ أَشْهُر إِلَى آخِرِ ذَلِكَ لِعَشْر خَلَوْنَ مِن المُحَرمِ".  

[Machine] Rajab is a great month; in it Allah multiplies good deeds. Whoever fasts one day of Rajab, it is as though he fasted a year; whoever fasts seven days of it, the gates of Hell are closed to him; whoever fasts eight days of it, the eight gates of Paradise are opened for him; whoever fasts ten days of it, he will ask Allah for nothing except that He gives it to him; whoever fasts fifteen days of it, a caller from the sky will call out: “You have been forgiven for what has passed, so begin your deeds anew.” And whoever does more, God will increase for him.

And in Rajab Allah carried Noah in the Ark, so he fasted Rajab and ordered those with him to fast; and the Ark carried them for six months, the end of that being the Day of Ashura, when it came down upon al-Judi. So Noah and those with him, and the wild beasts, fasted in thanks to God, Most Glorified and Exalted. And on the Day of Ashura Allah split the sea for the Children of Israel; and on the Day of Ashura Allah accepted the repentance of Adam and of the city of Jonah; and on it Abraham was born.  

"رجبٌ شَهْرٌ عظيمٌ، يضاعِفُ اللَّه فيهِ الحسنات، لمنْ صام يوْمًا مِنْ رجب فَكَأنَّما صام سنةً، ومنْ صام مِنْه سبْعةَ أَيَّام غُلِّقَتْ عَنْه أبْوابُ جهنَّمَ، ومنْ صام منْهُ ثَمانِيةَ أَيَّامٍ فُتِّحتْ لَه ثَمانِيةُ أَبْواب الجنِّةِ، ومنْ صام مِنهُ عشرةَ أَيَّامٍ لَمْ يسْأَل اللَّهَ شَيْئًا إِلَّا أَعْطَاه، ومنْ صام مِنْه خَمْسة عشَر يوْمًا نَادى منَاد مِنَ السَّماءِ، قَدْ غُفِر لَكَ ما مضَى فَاستَأْنْفِ العملَ، ومنْ زاد زَاده اللَّه، وفى رجبٍ حَملَ اللَّه نُوحًا في السَّفينةَ فَصام رجب، وأَمر مَنْ معه أَنْ يصوموا فَجرتْ بهمْ السَّفِينَةُ سِتَّةَ أَشْهر، آخِرُ ذَلَكَ الْيَوْم يوْم عاشُوراءَ، اهْبطَ علَى الجودِىِّ، فَصَام نُوحٌ ومنْ معه، والْوحْشُ شُكْرًا للَّهِ ﷻ وفى يَوْم عَاشُورَاءَ فلَقَ اللَّهُ البَحْرَ لبنى إِسْرائِيل وفى يوم عاشُوراءَ تَاب اللَّه علَى آدم وعلَى مدِينةِ يونُس، وفِيهِ وُلِد إِبْراهِيم".
