مسلم:٤٦٧d – وَحَدَّثَنَا عَبْدُ الْمَلِكِ بْنُ شُعَيْبِ بْنِ اللَّيْثِ حَدَّثَنِي أَبِي حَدَّثَنِي اللَّيْثُ بْنُ سَعْدٍ حَدَّثَنِي يُونُسُ عَنِ ابْنِ شِهَابٍ حَدَّثَنِي أَبُو بَكْرِ بْنُ عَبْدِ الرَّحْمَنِ أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ يَقُولُ

قَالَ رَسُولُ اللَّهِ ﷺ بِمِثْلِهِ غَيْرَ أَنَّهُ قَالَ بَدَلَ السَّقِيمِ الْكَبِيرَ
