وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، - رضى الله عنهما - أَنَّ رِجَالاً، مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم أُرُوا لَيْلَةَ الْقَدْرِ فِي الْمَنَامِ فِي السَّبْعِ الأَوَاخِرِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ أَرَى رُؤْيَاكُمْ قَدْ تَوَاطَأَتْ فِي السَّبْعِ الأَوَاخِرِ فَمَنْ كَانَ مُتَحَرِّيَهَا فَلْيَتَحَرَّهَا فِي السَّبْعِ الأَوَاخِرِ ‏"‏ ‏.‏

Zirr b. Hubaish reported that Ubayy b. Ka'b (Allah be pleased with him) said about Lailat-ul-Qadr

By Allah, I know well about it. Shu'ba said: To the best of my knowledge it was the twenty-seventh night for which the Messenger of Allah (ﷺ) commanded us to stand for prayer. Shu'ba doubted these words: That it was the night for which the Messenger of Allah (ﷺ) commanded us to stand for prayer. And (he further) said: This was narrated to me by a friend of mine from him (the Holy Prophet).
