وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَلِيُّ بْنُ مُسْهِرٍ، عَنِ الشَّيْبَانِيِّ، عَنْ جَبَلَةَ، وَمُحَارِبٍ عَنِ ابْنِ عُمَرَ، - رضى الله عنهما - قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " تَحَيَّنُوا لَيْلَةَ الْقَدْرِ فِي الْعَشْرِ الأَوَاخِرِ " . أَوْ قَالَ " فِي التِّسْعِ الأَوَاخِرِ " .
'Ibn 'Umar (Allah be pleased with both of them) reported Allah's Messenger (ﷺ) as saying: Seek the time of Lailat-ul-Qadr in the last (ten nights), or he said: in the last nine (nights).
