Narrated Ibn `Abbas:For the children of Israel the punishment for crime was Al-Qisas only (i.e., the law of equality in punishment) and the payment of Blood money was not permitted as an alternate. But Allah said to this nation (Muslims): 'O you who believe! Qisas is prescribed for you in case of murder, .....(up to) ...end of the Verse. (2.178) Ibn `Abbas added: Remission (forgiveness) in this Verse, means to accept the Blood-money in an intentional murder. Ibn `Abbas added: The Verse: 'Then the relatives should demand Blood-money in a reasonable manner.' (2.178) means that the demand should be reasonable and it is to be compensated with handsome gratitude
