[Machine] Ammar ibn Yasir said, "Whoever fasts on the day which is doubted (uncertain), has disobeyed Prophet Muhammad ﷺ ."  

عَمَّارُ بْنُ يَاسِرٍ «مَنْ صَامَ الْيَوْمَ الَّذِي يُشَكُّ فِيهِ فَقَدْ عَصَى أَبَا الْقَاسِمِ ﷺ»  

‘Do not anticipate Ramadan by fasting one or two days before, except for a man who has a habitual pattern of fasting, in which case let him fast.” (Using translation from Ibn Mājah 1650)   

قَالَ رَسُولُ اللَّهِ ﷺ «لَا تَقَدَّمُوا صِيَامَ شَهْرِ رَمَضَانَ بِصِيَامِ يَوْمٍ أَوْ يَوْمَيْنِ إِلَّا رَجُلٌ كَانَ يَصُومُ صِيَامًا فَلْيَصُمْهُ»  

[Machine] "The Prophet ﷺ said to him or to a man, 'Have you observed any voluntary fasts during this month?' He said, 'No.' He said, 'Then if you break your fast, observe a fast for one or two days.'"  

أَنَّ النَّبِيَّ ﷺ قَالَ لَهُ أَوْ لِرَجُلٍ «أَصُمْتَ مِنْ سَرَرِ هَذَا الشَّهْرِ شَيْئًا؟ » قَالَ لَا قَالَ «فَإِذَا أَفْطَرْتَ فَصُمْ يَوْمًا أَوْ يَوْمَيْنِ»  

The Messenger of Allah ﷺ asked a man: Did you fast the last day of Sha'ban ? He replied: No. He said: If you did not observe a fast, you must fast for a day. One of the two narrators said: For two days. (Using translation from Abū Dāʾūd 2328)   

أَنَّ رَسُولَ اللهِ ﷺ قَالَ لَهُ أوَ لِرَجُلٍ أَصُمْتَ مِنْ سَرَرِ شَعْبَانَ شَيْئًا قَالَ لَا قَالَ فَإِذَا أَفْطَرْتَ فَصُمْ يَوْمَيْنِ  

the Messenger of Allah ﷺ said, "When it is the middle of ˹the month of˺ Shaʿbān then break ˹from˺ fasting until ˹the month of˺ Ramaḍān arrives.”  

عَنِ النَّبِيِّ ﷺ قَالَ «إِذَا كَانَ النِّصْفُ مِنْ شَعْبَانَ فَأَفْطِرُوا حَتَّى يَجِيءَ رَمَضَانُ۔»  

[Machine] I entered upon Ikrimah on the day when the sighting of the new moon of Ramadan was being doubtful and he was eating, so I said, "Order me to eat (also)?" He said, "I am not ordering you to do that, for the Prophet ﷺ said, 'Fast when you see the crescent of Ramadan, and when you see the crescent of Dhul-Hijja, break your fast. If the sky is overcast (and you cannot see it), then complete thirty days of Sha'ban.'"  

دَخَلْتُ عَلَى عِكْرِمَةَ فِي الْيَوْمِ الَّذِي يُشَكُّ فِيهِ مِنْ رَمَضَانَ وَهُوَ يَأْكُلُ فَقَالَ ادْنُ فَكُلْ قُلْتُ إِنِّي صَائِمٌ فَقَالَ وَاللَّهِ لَتَدْنُوَنَّ قُلْتُ فَحَدِّثْنِي قَالَ حَدَّثَنِي ابْنُ عَبَّاسٍ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «لَا تَسْتَقْبِلُوا الشَّهْرَ اسْتِقْبَالًا صُومُوا لِرُؤْيَتِهِ وَأَفْطِرُوا لِرُؤْيَتِهِ فَإِنْ حَالَ بَيْنَكُمْ وَبَيْنَهُ غَبَرَةُ سَحَابٍ أَوْ قَتَرَةٌ فَأَكْمِلُوا الْعِدَّةَ ثَلَاثِينَ»  

from the Prophet ﷺ who said, "There ˹should be˺ no fasting after the middle of ˹the month of˺ Shaʿbān until the month of Ramaḍān arrives.”  

عَنْ رَسُولِ اللَّهِ ﷺ قَالَ «لَا صَوْمَ بَعْدَ النِّصْفِ مِنْ شَعْبَانَ حَتَّى يَجِيءَ شَهْرُ رَمَضَانَ۔»  

‘Do not anticipate Ramadan by fasting one or two days before, except for a man who has a habitual pattern of fasting, in which case let him fast.” (Using translation from Ibn Mājah 1650)   

قَالَ رَسُولُ اللَّهِ ﷺ «لَا تَقَدَّمُوا بَيْنَ يَدَيْ رَمَضَانَ بِيَوْمٍ أَوْ يَوْمَيْنِ إِلَّا رَجُلٌ كَانَ يَصُومُ صِيَامًا فَلْيَصُمْهُ»  

The month of Ramadan may consist of twenty-nine days. So do not fast till you have sighted it (the new moon) and do not break fast, till you have sighted it (the new moon of Shawwal), and if the sky is cloudy for you, then calculate. (Using translation from Muslim 1080e)  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «إِنَّمَا الشَّهْرُ تِسْعٌ وَعِشْرُونَ فَلَا تَصُومُوا حَتَّى تَرَوْهُ وَلَا تُفْطِرُوا حَتَّى تَرَوْهُ فَإِنْ أُغْمِيَ عَلَيْكُمْ فَاقْدُرُوا لَهُ»  

"The Messenger of Allah said: "The Messenger of Allah said: Do not fast before Ramadan. Fast when you see it and stop fasting when you see it, and if clouds prevent you from seeing it, then complete Thirty (Days)."' (Using translation from Nasāʾī 2130)  

قَالَ رَسُولُ اللَّهِ ﷺ «لَا تَصُومُوا قَبْلَ رَمَضَانَ صُومُوا لِرُؤْيَتِهِ وَأَفْطِرُوا لِرُؤْيَتِهِ فَإِنْ حَالَتْ دُونَهُ غَيَابَةٌ فَأَكْمِلُوا ثَلَاثِينَ»  

[Machine] Ammar ibn Yassir said, "Whoever fasts on the day they have doubts about, has disobeyed Abu al-Qasim ﷺ ."  

عَمَّارُبْنُ يَاسِرٍ «مَنْ صَامَ الْيَوْمَ الَّذِي يَشُكُّ فِيهِ فَقَدْ عَصَى أَبَا الْقَاسِمِ ﷺ»  

[Machine] Ammar ibn Yasir said, "Whoever fasts this day has disobeyed Abu Al-Qasim."  

عَمَّارُ بْنُ يَاسِرٍ «مَنْ صَامَ هَذَا الْيَوْمَ فَقَدْ عَصَى أَبَا الْقَاسِمِ»  

"Do not fast until you see the crescent, and do not stop fasting until you see it, and if it is obscured from you (too cloudy), then work it out." (Using translation from Nasāʾī 2121)   

قَالَ رَسُولُ اللَّهِ ﷺ «لَا تَصُومُوا حَتَّى تَرَوَا الْهِلَالَ وَلَا تُفْطِرُوا حَتَّى تَرَوْهُ إِلَّا أَنْ يُغَمَّ عَلَيْكُمْ فَإِنْ غُمَّ عَلَيْكُمْ فَاقْدُرُوا لَهُ»
