Is the killing of an individual by a group, in which Umar ibn al-Khattab ruled for qisas (retaliation) against seven people from Sana'a who colluded to kill one man, the same as what happened to my father who was killed by a bullet from one of them, while each of them intended to kill him and participated in the aggression? And is it a condition for the obligation of qisas that each one of them directly killed him, or is the intention to kill and participation in the aggression sufficient?

Issues of hudud (punishments) and qisas (retaliation) are referred to the Sharia courts. The majority of jurists hold that a group is to be killed for one person. If a group conspires to kill a person, and some of them directly commit the act leading to death, while others do not directly commit it but agreed beforehand to perpetrate it and were present as support for the killers, then jurists have differed on this matter. The majority of jurists are of the opinion that qisas is not obligatory upon those who did not directly commit the act leading to death, whereas the Malikis hold that qisas applies to all conspirators.
