Musannaf Ibn Abi Shaybah

Hazrat Amr bin Dinar narrates that Hazrat Jabir said: A man struck another man’s knee with the horn of a spear, so he came to the Prophet Muhammad (peace be upon him) to seek retribution. He was told to wait until he recovered, but he refused and insisted on immediate retribution. The narrator says: Then his leg broke again, and the leg of the one from whom retribution was taken became healthy. So he came to the Prophet Muhammad (peace be upon him), and he (peace be upon him) said: You have gained nothing; you refused (to wait).
