الطبراني:١٤٥٦٨حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ الْعَزِيزِ حَدَّثَنَا إِسْحَاقُ بْنُ إِسْمَاعِيلَ الطَّالَقَانِيُّ حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ عَنِ ابْنِ أَبِي نَجِيحٍ عَنْ مُجَاهِدٍ قَالَ

سَمِعْتُ رَجُلًا فِي مَسْجِدِ الْكُوفَةِ يَقُولُ «كُنْتُ يَوْمَ حَكَمَ سَعْدُ بْنُ مُعَاذٍ فِي بَنِي قُرَيْظَةَ غُلَامًا فَشَكُّوا بِي فَلَمْ يَجِدُوا الْمُوسَى جَرَتْ عَلَيَّ فَاسْتُبْقِيتُ»
