like the partner of a stranger. We do not concede that the father's act is not a warrant for retaliation; for it demands the obligation because it was purely intentional and hostile, and the crime involving it is greater in sin and more severe in offense, which is why Allah the Almighty specifically forbade it, saying: "And do not kill your children" [17:31]. Then He said: "Indeed, their killing is a great sin" [17:31]. When the Prophet, may Allah bless him and grant him peace, was asked about the greatest sin, he said: "That you set up a partner to Allah while He created you, then that you kill your child for fear that he might eat with you." He thus made it the greatest of sins after shirk (associating partners with Allah). Furthermore, he severed the ties of kinship that Allah the Almighty commanded to be maintained and placed harm where kindness was due; therefore, he is more deserving of the imposition of punishment and deterrent. The obligation was only withheld in the case of the father due to a meaning specific to the person (the father), not due to a deficiency in the cause that warrants it. Thus, it does not prevent its effect in the location where there is no impediment. As for the partner of the one who erred, we have a prohibition regarding that; and even if we were to concede it, the non-obligation in that case is due to the inadequacy of the cause to warrant it, for the act of the one who erred does not warrant retaliation nor is it fit for it, and the killing by him and his partner is not purely intentional due to the occurrence of error in the act that resulted in the loss of life, unlike our case.
Section: Every two partners for whom retaliation is prevented regarding one of them due to a meaning inherent in him—without any deficiency in the cause—is, in terms of the obligation of retaliation upon his partner, like the father and his partner. For example, if a Muslim and a Dhimmi (protected non-Muslim) participate in killing a Dhimmi, or a free person and a slave participate in killing a slave, intentionally and hostilely, then retaliation does not
