The Quran Never Allows Honor/Honour Killings!
The words honor and chastity are not included in the Qur’an (Fuat Aydin, “Namus,” Diyanet-Encyclopedia of Islam, XXII, 381; Hayati Hokelekli, “Irz,” Diyanet-Encyclopedia of Islam, XIX, 134).
In the Qur’an, it is commanded to be moral and to stay away from fornication with clear orders (For example: an-Nur  33).
However, if a woman has betrayed her husband by committing adultery, what can be done is to divorce her. Because the Qur’an does not in any way allow the murder of a woman who commits immorality and cheats on her husband (Rajm means the punishment of killing adulterers by stoning. Rajim is not in the Qur’an, but in the Torah (OT, Deuteronomy 22:22). The traditional understanding states that there is a penalty for stoning. However, this penalty is contrary to the Qur’an (al-Ahzab  30; an-Nisa  25). There is no such severe punishment in the Qur’an (an-Nisa  15; an-Nur  2).
“I cleared my honor!?” These reasons are not in accordance with the Qur’an. These are murders that Allah does not allow. The punishment for murder is stated in the Qur’an as Hell
(“He who kills a person unjustly and deliberately will be thrown into Hell indefinitely and his punishment will be multiplied.” (al-Furqan  68-69;an-Nisa  93).
