Islamic scholars state that whilst the Qur'an professes the basic principle that everyone has the right to life, this principle allows for an exception when a court of law demands it. Their precept is "Do not kill a Soul which Allah has made sacred except through the due process of law". This exception authorises the administration of capital punishment when Islamic law dictates. This is the line taken by most countries in which Islam is the state religion or the principal religion, for example, throughout the Arab world and in Indonesia and Malaysia. Moreover, in Islamic jurist theory, it is wrong to forbid something which is not forbidden.

One notable characteristic of Sharia is that the family of a murder victim can pardon the murderer. In Islam, the victim and/or the victim's family are the judges for all crimes; they decide what the punishment shall be under the supervision of a jurist who knows the Qur'an.

One verse which clearly illustrates the possibility of capital punishment is in the Qur’an verse 5:32. “On that account: We ordained for the Children of Israel that if any one slew a person - unless it be for murder or for spreading mischief in the land - it would be as if he slew the whole people: and if any one saved a life, it would be as if he saved the life of the whole people. Then although there came to them Our messengers with clear signs, yet, even after that, many of them continued to commit excesses in the land.” Other verses reinforce the idea that, for example, in a case of muder, the victim's family decides the punishment- with the death penalty as a possibilty. Verse 5:32 notes that compassion is the best choice. "Mischief in the land" (e.g. treason) is also punishable by death. Verse 2:178 further discusses capital punishment, in the case of murder; “O you who believe! retaliation is prescribed for you in the matter of the slain, the free for the free, and the slave for the slave, and the female for the female, but if any remission is made to any one by his (aggrieved) brother, then prosecution (for the bloodwit) should be made according to usage, and payment should be made to him in a good manner; this is an alleviation from your Lord and a mercy; so whoever exceeds the limit after this he shall have a painful chastisement.”

Here, it is further clarified that capital punishment is only just with the rule of equality (slave for slave, etc., a man killing a woman would not be justly punishable by death), and the idea of the victim's family receiving a payment to spare the murderer's life is presented. This payment, some Muslim thinkers hold, is more constructive in a case of a father being murdered- the murdered father's family has a better chance of survival without him if there is monetary compensation, whereas capital punishment would leave them without a breadwinner.
