حَدَّثَنَا مُحَمَّدُ بْنُ بَكْرٍ أَخْبَرَنَا ابْنُ جُرَيْجٍ حَدَّثَنِي الزُّهْرِيُّ عَنْ حَدِيثِ سَالِمِ بْنِ عَبْدِ اللَّهِ أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الْتَمِسُوا لَيْلَةَ الْقَدْرِ فِي السَّبْعِ الْأَوَاخِرِ مِنْ شَهْرِ رَمَضَانَ
