ابن حبّان:٧٤٨٨ – أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدِ بْنِ سَلْمٍ قَالَ حَدَّثَنَا حَرْمَلَةُ بْنُ يَحْيَى قَالَ حَدَّثَنَا ابْنُ وَهْبٍ قَالَ أَخْبَرَنَا عَمْرُو بْنُ الْحَارِثِ أَنَّ سُلَيْمَانَ بْنَ حُمَيْدٍ حَدَّثَهُ أَنَّ أَبَاهُ حَدَّثَهُ أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ يَقُولُ

قَالَ رَسُولُ اللَّهِ ﷺ «ضِرْسُ الْكَافِرِ مِثْلُ أُحُدٍ يَعْنِي فِي النَّارِ »
