[Machine] The Messenger of Allah ﷺ observed i'tikaf during the middle ten days of Ramadan while seeking Laylat al-Qadr before it was made clear to him. When it had elapsed, he commanded that a shelter be constructed but it was torn down. Then, it was revealed that it was in the last ten days, so he ordered for it to be reconstructed and observed i'tikaf during the last ten days. He then came out to the people and said, "I was informed of the night of Laylat al-Qadr, so I came out to inform you of it, but two men along with Satan came to me and I forgot it. So, seek it in the ninth, seventh, and fifth nights."  

الكبرى للنسائي:٣٣٩١أَخْبَرَنَا عَمْرُو بْنُ زُرَارَةَ قَالَ أَخْبَرَنَا إِسْمَاعِيلُ عَنْ سَعِيدٍ الْجُرَيْرِيِّ عَنْ أَبِي نَضْرَةَ عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ قَالَ

اعْتَكَفَ رَسُولُ اللهِ ﷺ الْعَشْرَ الْأَوْسَطَ مِنْ رَمَضَانَ وَهُوَ يَلْتَمِسُ لَيْلَةَ الْقَدْرِ قَبْلَ أَنْ تُبَانَ لَهُ فَلَمَّا انْقَضَيْنَ أَمَرَ بِالْبِنَاءِ فَنُقِضَ ثُمَّ «أُبِينَتْ أَنَّهَا فِي الْعَشْرِ الْأَوَاخِرِ» فَأَمَرَ بِالْبِنَاءِ فَأُعِيدَ وَاعْتَكَفَ الْعَشْرَ الْأَوَاخِرَ فَخَرَجَ عَلَى النَّاسِ فَقَالَ «إِنِّي أُنْبِئْتُ لَيْلَةَ الْقَدْرِ فَخَرَجْتُ لِأُخْبِرَكُمْ بِهَا فَجَاءَ رَجُلَانِ مَعَهُمَا الشَّيْطَانُ فَنَسِيتُهَا فَالْتَمِسُوهَا فِي التَّاسِعَةِ وَفِي السَّابِعَةِ وَفِي الْخَامِسَةِ»

[Machine] The Messenger of Allah ﷺ performed Itikaf during the middle ten days of Ramadan, seeking Laylat al-Qadr (the Night of Decree) before it was revealed to him. When those ten days were complete, he commanded for a structure to be built, and it was built but then collapsed. Then it was revealed to him that Laylat al-Qadr was in the last ten days, so he commanded for it to be rebuilt. He then performed Itikaf during the last ten days, and then he emerged to address the people. He said, "O people, it has been revealed to me that Laylat al-Qadr was made known to me, but two feeble men with the devil made me forget it. So seek it in the ninth, seventh, and fifth nights." I (Abu Sa'id) said, "Indeed, you know the number of us better." He replied, "I am more entitled to do that than you. So leave aside the twenty-first night, and the ninth night follows it, and leave aside the twenty-third night, and the seventh night follows it, and leave aside the twenty-fifth night, and the fifth night follows it."

[Machine] The Messenger of Allah ﷺ observed I'tikaf during the middle ten days of Ramadan, while seeking the Night of Qadr. When those days had passed, he ordered the construction to be torn down and it was revealed to him that it was in the last ten days of Ramadan. So he came out to the people and said, "O people, indeed I was informed about the Night of Qadr, but I was made to forget it, so search for it in the seventh night or in the fifth night."
