Honor killing is forbidden in Islam.There is no specific mention of the practice in the Qur'an or Hadiths except in so far as the custom of killing baby girls to protect the family honor, which is specifically condemned in the Qur'an, was a form of honor killing.
Like all other religions, Islam strictly prohibits murder and killing without legal justification. Allah, Most High, says, “Whoso slayeth a believer of set purpose, his reward is Hell for ever. Allah is wroth against him and He hath cursed him and prepared for him an awful doom.” (An-Nisa’: 93) The so-called “honor killing” is based on ignorance and disregard of morals and laws, which cannot be abolished except by disciplinary punishments.
