暴政与压迫是最严重的罪恶之一,因为它们违背了公正,而天地正是建立在公正之上。真主 ~ 派遣使者并降下经典,目的是让人们在彼此之间建立公正。无权无故地非法杀人,是一桩大罪。伊斯兰教列举了许多此类恶行的例子,比如因担心孩子会分享自己的生计(即食物、饮水和钱财)而杀害子女;杀害生养自己的父母;杀害自己的亲属。这类恶行的严重程度因行为本身的性质而有所不同。因此,在复活日受到最严厉惩罚的人,是杀害先知的人,其次是杀害伊玛目,或是杀害那些command公正、引导人们走上真主之道的学者。真主 ~ 为故意杀害信士者所规定的惩罚,是永居火狱,并承受主的诅咒与震怒。

Tyranny and oppression are among the greatest sins because they oppose justice, upon which the heavens and the earth were established. Allah ~ sent His Messengers and Books in order that people might establish justice among themselves. The act of killing unlawfully, without any right, is a great sin. Islam cites many examples of such evil acts, like the killing of one's child for fear that the child might share one's provision (i.e. food, drink, and money); the killing of one's parents who were the cause of one's existence; the killing of one's kin. The grade of such an evil act differs according to the nature of the act itself; therefore, the person who will receive the utmost punishment on the Day of Resurrection is the one who killed a prophet, followed by the one who killed an Imam, or a scholar who commanded justice among people and invited them to the Path of Allah ~- Allah ~ has set the punishment for the intentional killing of a believer as dwelling eternally in the Hell-Fire, with the Curse and Anger of the Lord.
