bukhari:788Mūsá b. Ismāʿīl > Hammām > Qatādah > ʿIkrimah

البخاري:٧٨٨حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ قَالَ أَخْبَرَنَا هَمَّامٌ عَنْ قَتَادَةَ عَنْ عِكْرِمَةَ قَالَ

صَلَّيْتُ خَلْفَ شَيْخٍ بِمَكَّةَ فَكَبَّرَ ثِنْتَيْنِ وَعِشْرِينَ تَكْبِيرَةً فَقُلْتُ لاِبْنِ عَبَّاسٍ إِنَّهُ أَحْمَقُ فَقَالَ ثَكِلَتْكَ أُمُّكَ سُنَّةُ أَبِي الْقَاسِمِ ﷺ وَقَالَ مُوسَى حَدَّثَنَا أَبَانُ حَدَّثَنَا قَتَادَةُ حَدَّثَنَا عِكْرِمَةُ
