Word reached Musab bin Zubayr about the chief of the Ansar concerning something that troubled him, and he was about to take action against him. Then Anas bin Malik came in to see him and said, "I heard the Messenger of Allah ﷺ say, 'Treat the Ansar well,'" or he said, "'with kindness. Accept from those of them who do good, and overlook the faults of those who do wrong.'"At this, Musab threw himself down from his couch, pressed his cheek against the carpet, and said, "The command of the Messenger of Allah ﷺ is upon my head and my eye." So he let the man go.
حدثنا مؤمل حدثنا حماد يعني ابن سلمة
بلغ مصعب بن الزبير عن عريف الأنصار شيء فهم به فدخل عليه أنس بن مالك فقال له سمعت رسول الله ﷺ يقول استوصوا بالأنصار خيرا أو قال معروفا اقبلوا من محسنهم وتجاوزوا عن مسيئهم فألقى مصعب نفسه عن سريره وألزق خده بالبساط وقال أمر رسول الله ﷺ على الرأس والعين فتركه
