Ata bin Abi Maymunah (may Allah have mercy on him) said: I know it only from Sayyiduna Anas (may Allah be pleased with him) that whenever a case of retaliation was brought to him (peace and blessings be upon him), he advised pardon in it. He said: I said to Affan (may Allah have mercy on him): "Who has doubt about it?" He said: Abdullah (may Allah have mercy on him) said: "I used to say 'from Anas (may Allah be pleased with him)'," and they said: "Do not doubt about it." I said: "I do not know it." And he was a very intelligent and astute man.
