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  

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

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)
