Abu Safar says: A man from the Quraysh broke the tooth of an Ansari man. The Ansari went to seek justice from Sayyiduna Amir Muawiyah (may Allah be pleased with him). The Ansari said: He has broken my tooth. Sayyiduna Muawiyah (may Allah be pleased with him) said: Surely, we will satisfy you. When the Ansari insisted on taking retribution, Sayyiduna Amir Muawiyah (may Allah be pleased with him) said: Your matter is in the hands of your companion. Sayyiduna Abu Darda (may Allah be pleased with him) was sitting nearby; he said that the Messenger of Allah (peace and blessings be upon him) said: Whoever among the Muslims forgives a wound inflicted upon his body, Allah Almighty raises his rank and erases his sin. The Ansari said: Did you hear this hadith from the Messenger of Allah (peace and blessings be upon him)? He said: Yes! My ears heard it and my heart remembered it. So the Ansari forgave the Qurayshi.
Hadith Takhrij«المرفوع منه صحيح لغيره، وھذا اسناد ضعيف لانقطاعه، ابو السفر، قال احمد: لا اعرف له سماعا من ابي الدردائ، بل قال الحافظ: ما اظنه ادركه، فان ابا الدرداء قديم الموت۔ أخرجه الترمذي: 1393، وابن ماجه: 2693، (انظر مسند أحمد ترقيم الرسالة: 27534 ترقیم بيت الأفكار الدولية: 28084»
It is narrated from Sayyiduna ‘Ubada bin Samit (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: When a person is wounded in his body and he forgives (the one who wounded him), then Allah Almighty erases his sins in proportion to his forgiveness.
It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that whenever a case involving retribution (qisas) was presented to the Noble Prophet (peace and blessings be upon him), he (peace and blessings be upon him) would first command forgiveness.
