It is narrated from Sayyiduna Abu Shurayh that the Prophet (peace be upon him) said: If a person's blood is shed or he is wounded, he has the choice of one of three things: either he takes retribution (qisas), or he accepts blood money (diyah), or he forgives. If he wants to choose a fourth option besides these, restrain his hand. If he chooses one of these three and then, acting rebelliously, kills (the offender), then for him is Hell, where he will abide forever.
