Suicide is a major sin in Islam. Prophet Muhammad stated that the one who commits suicide will be punished with what he used to kill himself. Suicide is not disbelief that puts a person beyond the pale of Islam, as some people think. Rather it is a major sin that is subject to the Will of Allah on the Day of Resurrection: if He Wills, He will forgive it, and if He Wills He will punish for it. The Prophet refrained from offering the funeral prayer for one who had committed suicide, as a punishment to him and so as to deter others from doing the same. But he allowed people to offer the funeral prayer for him, so it is Sunnah for the people of knowledge and virtue not to offer the funeral prayer for one who has committed suicide.
