Messenger of Allah ﷺ used to practice Iʿtikaf in the middle ten days of Ramadan and once he stayed in Iʿtikaf till the night of the twenty-first and it was the night in the morning of which he used to come out of his Iʿtikaf. The Prophet ﷺ said, "Whoever was in Iʿtikaf with me should stay in Iʿtikaf for the last ten days, for I was informed (of the date) of the Night (of Qadr) but I have been caused to forget it. (In the dream) I saw myself prostrating in mud and water in the morning of that night. So, look for it in the last ten nights and in the odd ones of them." It rained that night and the roof of the mosque dribbled as it was made of leaf stalks of date-palms. I saw with my own eyes the mark of mud and water on the forehead of the Prophet (i.e. in the morning of the twenty-first).  

عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ ؓ أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَعْتَكِفُ فِي الْعَشْرِ الأَوْسَطِ مِنْ رَمَضَانَ فَاعْتَكَفَ عَامًا حَتَّى إِذَا كَانَ لَيْلَةَ إِحْدَى وَعِشْرِينَ وَهِيَ اللَّيْلَةُ الَّتِي يَخْرُجُ مِنْ صَبِيحَتِهَا مِنِ اعْتِكَافِهِ قَالَ مَنْ كَانَ اعْتَكَفَ مَعِي فَلْيَعْتَكِفِ الْعَشْرَ الأَوَاخِرَ وَقَدْ أُرِيتُ هَذِهِ اللَّيْلَةَ ثُمَّ أُنْسِيتُهَا وَقَدْ رَأَيْتُنِي أَسْجُدُ فِي مَاءٍ وَطِينٍ مِنْ صَبِيحَتِهَا فَالْتَمِسُوهَا فِي الْعَشْرِ الأَوَاخِرِ وَالْتَمِسُوهَا فِي كُلِّ وِتْرٍ فَمَطَرَتِ السَّمَاءُ تِلْكَ اللَّيْلَةَ وَكَانَ الْمَسْجِدُ عَلَى عَرِيشٍ فَوَكَفَ الْمَسْجِدُ فَبَصُرَتْ عَيْنَاىَ رَسُولَ اللَّهِ ﷺ عَلَى جَبْهَتِهِ أَثَرُ الْمَاءِ وَالطِّينِ مِنْ صُبْحِ إِحْدَى وَعِشْرِينَ  

I used to devote myself (observe i'tikaf) during these ten (nights). Then I started devoting myself in the last ten (nights). And he who desires to observe i'tikaf along with me should spend the night) at his place of i'tikaf. And I saw this night (Lailat-ul-Qadr) but I forgot it (the exact night) ; so seek it;In the last ten nights on odd numbers. I saw (the glimpses of that dream) that I was prostrating in water and mud. Abu Sa'id al-Khudri said: It rained on the twenty-first night and the water dripped (from the roof) of the mosque at the place where the Messenger of Allah ﷺ observed prayer. I looked at him and as he completed the dawn prayer, (I found) his face was wet with mud and water.  

عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ ؓ قَالَ كَانَ رَسُولُ اللَّهِ ﷺ يُجَاوِرُ فِي الْعَشْرِ الَّتِي فِي وَسَطِ الشَّهْرِ فَإِذَا كَانَ مِنْ حِينِ تَمْضِي عِشْرُونَ لَيْلَةً وَيَسْتَقْبِلُ إِحْدَى وَعِشْرِينَ يَرْجِعُ إِلَى مَسْكَنِهِ وَرَجَعَ مَنْ كَانَ يُجَاوِرُ مَعَهُ ثُمَّ إِنَّهُ أَقَامَ فِي شَهْرٍ جَاوَرَ فِيهِ تِلْكَ اللَّيْلَةَ الَّتِي كَانَ يَرْجِعُ فِيهَا فَخَطَبَ النَّاسَ فَأَمَرَهُمْ بِمَا شَاءَ اللَّهُ ثُمَّ قَالَ إِنِّي كُنْتُ أُجَاوِرُ هَذِهِ الْعَشْرَ ثُمَّ بَدَا لِي أَنْ أُجَاوِرَ هَذِهِ الْعَشْرَ الأَوَاخِرَ فَمَنْ كَانَ اعْتَكَفَ مَعِي فَلْيَبِتْ فِي مُعْتَكَفِهِ وَقَدْ رَأَيْتُ هَذِهِ اللَّيْلَةَ فَأُنْسِيتُهَا فَالْتَمِسُوهَا فِي الْعَشْرِ الأَوَاخِرِ فِي كُلِّ وِتْرٍ وَقَدْ رَأَيْتُنِي أَسْجُدُ فِي مَاءٍ وَطِينٍ قَالَ أَبُو سَعِيدٍ الْخُدْرِيُّ مُطِرْنَا لَيْلَةَ إِحْدَى وَعِشْرِينَ فَوَكَفَ الْمَسْجِدُ فِي مُصَلَّى رَسُولِ اللَّهِ ﷺ فَنَظَرْتُ إِلَيْهِ وَقَدِ انْصَرَفَ مِنْ صَلاَةِ الصُّبْحِ وَوَجْهُهُ مُبْتَلٌّ طِينًا وَمَاءً  

I observed i'tikaf in the first ten (nights and days) in order to seek that night (Lailat-ul-Qadr). I then observed i'tikaf in the middle ten days. Then (an angel) was sent to me and I was told that this (night) is among the last ten (nights). He who among you likes to observe i'tikaf should do so; and the people observed it along with him, and he (the Holy Prophet) said: That (Lailat-ul-Qadr) was shown to me on an odd (night) and I (saw in the dream) that I was prostrating in the morning in clay and water. So in the morning of the twenty-first night when he (the Holy Prophet) got up for dawn (prayer). there was a rainfall and the mosque dripped, and I saw clay and water. When he came out after completing the morning prayer (I saw) that his forehead and the tip of his nose had (traces) of clay and water, and that was the twenty-first night among the last ten (nights).  

عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ ؓ قَالَ إِنَّ رَسُولَ اللَّهِ ﷺ اعْتَكَفَ الْعَشْرَ الأَوَّلَ مِنْ رَمَضَانَ ثُمَّ اعْتَكَفَ الْعَشْرَ الأَوْسَطَ فِي قُبَّةٍ تُرْكِيَّةٍ عَلَى سُدَّتِهَا حَصِيرٌ قَالَ فَأَخَذَ الْحَصِيرَ بِيَدِهِ فَنَحَّاهَا فِي نَاحِيَةِ الْقُبَّةِ ثُمَّ أَطْلَعَ رَأْسَهُ فَكَلَّمَ النَّاسَ فَدَنَوْا مِنْهُ فَقَالَ إِنِّي اعْتَكَفْتُ الْعَشْرَ الأَوَّلَ أَلْتَمِسُ هَذِهِ اللَّيْلَةَ ثُمَّ اعْتَكَفْتُ الْعَشْرَ الأَوْسَطَ ثُمَّ أُتِيتُ فَقِيلَ لِي إِنَّهَا فِي الْعَشْرِ الأَوَاخِرِ فَمَنْ أَحَبَّ مِنْكُمْ أَنْ يَعْتَكِفَ فَلْيَعْتَكِفْ فَاعْتَكَفَ النَّاسُ مَعَهُ قَالَ وَإِنِّي أُرِيتُهَا لَيْلَةَ وِتْرٍ وَأَنِّي أَسْجُدُ صَبِيحَتَهَا فِي طِينٍ وَمَاءٍ فَأَصْبَحَ مِنْ لَيْلَةِ إِحْدَى وَعِشْرِينَ وَقَدْ قَامَ إِلَى الصُّبْحِ فَمَطَرَتِ السَّمَاءُ فَوَكَفَ الْمَسْجِدُ فَأَبْصَرْتُ الطِّينَ وَالْمَاءَ فَخَرَجَ حِينَ فَرَغَ مِنْ صَلاَةِ الصُّبْحِ وَجَبِينُهُ وَرَوْثَةُ أَنْفِهِ فِيهِمَا الطِّينُ وَالْمَاءُ وَإِذَا هِيَ لَيْلَةُ إِحْدَى وَعِشْرِينَ مِنَ الْعَشْرِ الأَوَاخِرِ  

The Messenger of Allah ﷺ used to spend the middle ten days of Ramadan in retirement and devotion (i'tikaf) in the mosque. One year he had retirement and devotion in the mosque (as usual); when the twenty-first night came, and this night when he used to come out his devotion in the mosque, he said: He who has engaged himself in devotion along with me should do so during the last ten days; I saw that night, that was caused to forget it, but I have seen myself prostrating in water and mud on the morning following (that night), so seek it in the last ten days and seek it every night with an odd number. Abu sa'id said: Rain fell that night, the mosque that was thatched building dripped, and my eyes saw the Messenger of Allah ﷺ with the traces of water and mud, on his forehead on the morning following the twenty-first night.  

كَانَ رَسُولُ اللَّهِ ﷺ يَعْتَكِفُ الْعَشْرَ الأَوْسَطَ مِنْ رَمَضَانَ فَاعْتَكَفَ عَامًا حَتَّى إِذَا كَانَتْ لَيْلَةُ إِحْدَى وَعِشْرِينَ وَهِيَ اللَّيْلَةُ الَّتِي يَخْرُجُ فِيهَا مِنَ اعْتِكَافِهِ قَالَ مَنْ كَانَ اعْتَكَفَ مَعِي فَلْيَعْتَكِفِ الْعَشْرَ الأَوَاخِرَ وَقَدْ رَأَيْتُ هَذِهِ اللَّيْلَةَ ثُمَّ أُنْسِيتُهَا وَقَدْ رَأَيْتُنِي أَسْجُدُ مِنْ صَبِيحَتِهَا فِي مَاءٍ وَطِينٍ فَالْتَمِسُوهَا فِي الْعَشْرِ الأَوَاخِرِ وَالْتَمِسُوهَا فِي كُلِّ وِتْرٍ قَالَ أَبُو سَعِيدٍ فَمُطِرَتِ السَّمَاءُ مِنْ تِلْكَ اللَّيْلَةِ وَكَانَ الْمَسْجِدُ عَلَى عَرِيشٍ فَوَكَفَ الْمَسْجِدُ فَقَالَ أَبُو سَعِيدٍ فَأَبْصَرَتْ عَيْنَاىَ رَسُولَ اللَّهِ ﷺ وَعَلَى جَبْهَتِهِ وَأَنْفِهِ أَثَرُ الْمَاءِ وَالطِّينِ مِنْ صَبِيحَةِ إِحْدَى وَعِشْرِينَ  

Yahya related to me from Malik from Yazid ibn Abdullah ibn al- Hadi from Muhammad ibn Ibrahim al-Harith at-Taymi from Abu Salama ibn Abd ar-Rahman that Abu Said al-Khudri said, "The Messenger of Allah ﷺ used to do itikaf in the middle ten days of Ramadan. One year he was doing itikaf and then, when it came to the night of the twenty-first, which was the night before the morning when he would normally have finished his itikaf, he said, 'Whoever has done i'tikaf with me should continue doing itikaf for the last ten days. I saw a certain night and then I was made to forget it. I saw myself prostrating the following morning in water and clay. Look for it in the last ten days, and look for it on the odd days.' " Abu Said continued, "The sky poured with rain that night and the mosque had a roof (made of palm fronds) and the mosque was soaked. With my own eyes I saw the Messenger of Allah ﷺ leave with traces of water and clay on his forehead and nose, in the morning after the night of the twenty- first."  

أَنَّهُ قَالَ كَانَ رَسُولُ اللَّهِ ﷺ يَعْتَكِفُ الْعَشْرَ الْوُسُطَ مِنْ رَمَضَانَ فَاعْتَكَفَ عَامًا حَتَّى إِذَا كَانَ لَيْلَةَ إِحْدَى وَعِشْرِينَ وَهِيَ اللَّيْلَةُ الَّتِي يَخْرُجُ فِيهَا مِنْ صُبْحِهَا مِنَ اعْتِكَافِهِ قَالَ مَنِ اعْتَكَفَ مَعِي فَلْيَعْتَكِفِ الْعَشْرَ الأَوَاخِرَ وَقَدْ رَأَيْتُ هَذِهِ اللَّيْلَةَ ثُمَّ أُنْسِيتُهَا وَقَدْ رَأَيْتُنِي أَسْجُدُ مِنْ صُبْحِهَا فِي مَاءٍ وَطِينٍ فَالْتَمِسُوهَا فِي الْعَشْرِ الأَوَاخِرِ وَالْتَمِسُوهَا فِي كُلِّ وِتْرٍ قَالَ أَبُو سَعِيدٍ فَأُمْطِرَتِ السَّمَاءُ تِلْكَ اللَّيْلَةَ وَكَانَ الْمَسْجِدُ عَلَى عَرِيشٍ فَوَكَفَ الْمَسْجِدُ قَالَ أَبُو سَعِيدٍ فَأَبْصَرَتْ عَيْنَاىَ رَسُولَ اللَّهِ ﷺ انْصَرَفَ وَعَلَى جَبْهَتِهِ وَأَنْفِهِ أَثَرُ الْمَاءِ وَالطِّينِ مِنْ صُبْحِ لَيْلَةِ إِحْدَى وَعِشْرِينَ  

[Machine] "Some people, indeed, observe it every year. So we went to Abu Sa'id al-Khudri and I said, 'O Abu Sa'id, did you hear the Messenger of Allah ﷺ mentioning the Night of Qadr?' He said, 'Yes, the Messenger of Allah ﷺ observed i'tikaf during the middle ten days of Ramadan and we also observed it with him. Then, when the morning of the twentieth day came, he returned and we returned with him. And he indicated the Night of Qadr for us, but then I forgot it.' So he said, 'Indeed, I saw the Night of Qadr, but then I forgot it. And in my vision, I saw myself prostrating in mud and water. Whoever observes i'tikaf with me, let him return to his i'tikaf and seek it in the last ten nights, in the odd-numbered nights. And on the last of those nights, the sky poured down rain upon us. And half of the mosque was covered with palm leaves and twigs.' And he, who is the most honorable and upon whom Allah sent down the Book, led us in the Maghrib prayer on the twenty-first night. Indeed, his forehead and the bridge of his nose were covered with water and mud."

The Messenger of Allah ﷺ used to spend the middle ten days of Ramadan in retirement and devotion (i'tikaf) in the mosque. One year he had retirement and devotion in the mosque (as usual); when the twenty-first night came, and this night when he used to come out his devotion in the mosque, he said: He who has engaged himself in devotion along with me should do so during the last ten days; I saw that night, that was caused to forget it, but I have seen myself prostrating in water and mud on the morning following (that night), so seek it in the last ten days and seek it every night with an odd number. Abu sa'id said: Rain fell that night, the mosque that was thatched building dripped, and my eyes saw the Messenger of Allah ﷺ with the traces of water and mud, on his forehead on the morning following the twenty-first night. (Using translation from Abū Dāʾūd 1382)   

أَنَّهُ قَالَ كَانَ رَسُولُ اللهِ ﷺ يَعْتَكِفُ الْعَشْرَ الْوَسَطَ مِنْ رَمَضَانَ فَاعْتَكَفَ عَامًا حَتَّى إِذَا كَانَ لَيْلَةُ إِحْدَى وَعِشْرِينَ وَهِيَ اللَّيْلَةُ الَّتِي يَخْرُجُ مِنْهَا مِنَ اعْتِكَافِهِ قَالَ مَنِ اعْتَكَفَ مَعِي فَلْيَعْتَكِفِ الْعَشْرَ الْأَوَاخِرَ وَقَدْ رَأَيْتُ هَذِهِ اللَّيْلَةَ ثُمَّ أُنْسِيتُهَا وَقَدْ رَأَيْتُنِي أَسْجُدُ صَبِيحَتَهَا فِي مَاءٍ وَطِينٍ فَالْتَمِسُوهَا فِي الْعَشْرِ الْأَوَاخِرِ وَالْتَمِسُوهَا فِي كُلِّ وِتْرٍ قَالَ أَبُو سَعِيدٍ فَمَطَرَتْ تِلْكَ اللَّيْلَةُ وَكَانَ الْمَسْجِدُ عَلَى عَرِيشٍ فَوُكِفَ الْمَسْجِدُ قَالَ أَبُو سَعِيدٍ فَأَبْصَرَتْ عَيْنَايَ رَسُولَ اللهِ ﷺ وَعَلَى جَبْهَتِهِ وَأَنْفِهِ أَثَرُ الْمَاءِ وَالطِّينِ صَبِيحَةَ إِحْدَى وَعِشْرِينَ  

I observed i'tikaf in the first ten (nights and days) in order to seek that night (Lailat-ul-Qadr). I then observed i'tikaf in the middle ten days. Then (an angel) was sent to me and I was told that this (night) is among the last ten (nights). He who among you likes to observe i'tikaf should do so; and the people observed it along with him, and he (the Holy Prophet) said: That (Lailat-ul-Qadr) was shown to me on an odd (night) and I (saw in the dream) that I was prostrating in the morning in clay and water. So in the morning of the twenty-first night when he (the Holy Prophet) got up for dawn (prayer). there was a rainfall and the mosque dripped, and I saw clay and water. When he came out after completing the morning prayer (I saw) that his forehead and the tip of his nose had (traces) of clay and water, and that was the twenty-first night among the last ten (nights). (Using translation from Muslim 1167c)   

أَنَّ رَسُولَ اللهِ ﷺ اعْتَكَفَ الْعَشْرَ الْأُوَلَ مِنْ رَمَضَانَ ثُمَّ اعْتَكَفَ الْعَشْرَ الْأَوْسَطَ فِي قُبَّةٍ تُرْكِيَّةٍ عَلَى سُدَّتِهَا حَصِيرٌ قَالَ فَأَخَذَ الْحَصِيرَ بِيَدِهِ فَنَحَّاهَا فِي نَاحِيَةِ الْقُبَّةِ ثُمَّ أَطْلَعَ رَأْسَهُ فَكَلَّمَ النَّاسَ فَدَنَوْا مِنْهُ فَقَالَ إِنِّي اعْتَكَفْتُ الْعَشْرَ الْأُوَلَ الْتَمِسْ هَذِهِ اللَّيْلَةَ ثُمَّ اعْتَكَفْتُ الْعَشْرَ الْأَوْسَطَ ثُمَّ أَتَيْتُ فَقِيلَ لِي إِنَّهَا فِي الْعَشْرِ الْأَوَاخِرِ فَمَنْ أَحَبَّ مِنْكُمْ أَنْ يَعْتَكِفَ فَلْيَعْتَكِفْ فَاعْتَكَفَ النَّاسُ مَعَهُ قَالَ وَإِنِّي رَأَيْتُهَا لَيْلَةَ وِتْرٍ وَإِنِّي أَسْجُدُ فِي صَبِيحَتِهَا فِي طِينٍ وَمَاءٍ فَأَصْبَحَ فِي لَيْلَةِ إِحْدَى وَعِشْرِينَ وَقَدْ قَامَ إِلَى الصُّبْحِ فَمَطَرَتِ السَّمَاءُ فَوُكِفَ الْمَسْجِدُ فَأَبْصَرْتُ الطِّينَ وَالْمَاءَ فَخَرَجَ حِينَ فَرَغَ مِنْ صَلَاةِ الصُّبْحِ وَجَبِينُهُ وَرَوْثَةُ أَنْفِهِ فِيهَا الطِّينُ وَالْمَاءُ وَإِذَا هِيَ لَيْلَةُ إِحْدَى وَعِشْرِينَ مِنَ الْعَشْرِ الْأَوَاخِرِ
