Sayyiduna Jabir (may Allah be pleased with him) narrates: A case was brought before the Prophet (peace and blessings be upon him) regarding a man who had struck someone on his thigh with a horn, injuring his thigh. He said: O Messenger of Allah! Grant me retribution (qisas). The Prophet (peace and blessings be upon him) said:“Treat the wound, and wait for a while until we see what happens to the injury.”He said: O Messenger of Allah! Grant me retribution. The Prophet (peace and blessings be upon him) again told him the same thing, but the man insisted: O Messenger of Allah! Grant me retribution. So the Prophet (peace and blessings be upon him) allowed him to take retribution. As a result, his (the claimant’s) leg swelled up, while the leg of the one from whom retribution was taken became fine. So the Prophet (peace and blessings be upon him) invalidated his compensation (diyah).
