The Messenger of Allah ﷺ gave us an address and said: The best of you is the one who defends his tribe, so long as he commits no sin. Abu Dawud said: Abu Ayyub b. Suwaid is weak.  

أبو داود:٥١٢٠حَدَّثَنَا أَحْمَدُ بْنُ عَمْرِو بْنِ السَّرْحِ حَدَّثَنَا أَيُّوبُ بْنُ سُوَيْدٍ عَنْ أُسَامَةَ بْنِ زَيْدٍ أَنَّهُ سَمِعَ سَعِيدَ بْنَ الْمُسَيَّبِ يُحَدِّثُ عَنْ سُرَاقَةَ بْنِ مَالِكِ بْنِ جُعْشُمٍ الْمُدْلِجِيِّ قَالَ

خَطَبَنَا رَسُولُ اللَّهِ ﷺ فَقَالَ خَيْرُكُمُ الْمُدَافِعُ عَنْ عَشِيرَتِهِ مَا لَمْ يَأْثَمْ  

قَالَ أَبُو دَاوُدَ أَيُّوبُ بْنُ سُوَيْدٍ ضَعِيفٌ
