حَدَّثَنَا عَفَّانُ حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ حَدَّثَنَا عَاصِمٌ عَنْ زِرٍّ قَالَ: قُلْتُ لِأُبَيِّ بْنِ كَعْبٍ: أَبَا الْمُنْذِرِ أَخْبِرْنِي عَنْ لَيْلَةِ الْقَدْرِ فَذَكَرَ الْحَدِيثَ، قَالَ: فَقُلْتُ: يَا أَبَا الْمُنْذِرِ أَنَّى عَلِمْتَ ذَلِكَ؟ قَالَ: بِالْآيَةِ الَّتِي أَخْبَرَنَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ
