الترمذي:٣٩٣٢أَخْبَرَنَا سُفْيَانُ بْنُ وَكِيعٍ قَالَ حَدَّثَنَا يَحْيَى بْنُ آدَمَ عَنْ أَبِي بَكْرِ بْنِ عَيَّاشٍ قَالَ حَدَّثَنَا صَالِحُ بْنُ أَبِي صَالِحٍ مَوْلَى عَمْرِو بْنِ حُرَيْثٍ قَالَ

سَمِعْتُ أَبَا هُرَيْرَةَ يَقُولُ ذُكِرَتِ الأَعَاجِمُ عِنْدَ النَّبِيِّ ﷺ فَقَالَ النَّبِيُّ ﷺ لأَنَا بِهِمْ أَوْ بِبَعْضِهِمْ أَوْثَقُ مِنِّي بِكُمْ أَوْ بِبَعْضِكُمْ هَذَا حَدِيثٌ غَرِيبٌ لاَ نَعْرِفُهُ إِلاَّ مِنْ حَدِيثِ أَبِي بَكْرِ بْنِ عَيَّاشٍ وَصَالِحُ بْنُ أَبِي صَالِحٍ هَذَا يُقَالُ لَهُ صَالِحُ بْنُ مِهْرَانَ مَوْلَى عَمْرِو بْنِ حُرَيْثٍ
