البيهقي:٢١٠٨٠ – حَدَّثَنَا أَبُو مُحَمَّدِ بْنُ يُوسُفَ أنبأ أَبُو مُحَمَّدٍ عَبْدُ اللهِ بْنُ مُحَمَّدِ بْنِ إِسْحَاقَ ثنا أَبُو يَحْيَى بْنُ أَبِي مَسَرَّةَ ثنا يَحْيَى بْنُ قَزَعَةَ ثنا إِسْرَائِيلُ عَنْ سِمَاكِ بْنِ حَرْبٍ عَنْ عَبْدِ الرَّحْمَنِ بْنِ عَبْدِ اللهِ بْنِ مَسْعُودٍ عَنْ أَبِيهِ قَالَ

قَالَ رَسُولُ اللهِ ﷺ مَنْ أَعَانَ عَلَى ظُلْمٍ فَهُوَ كَالْبَعِيرِ الْمُتَرَدِّي فَهُوَ يَنْزِعُ بِذَنَبِهِ وَرَوَاهُ زُهَيْرُ بْنُ مُعَاوِيَةَ عَنْ سِمَاكٍ مَوْقُوفًا
