Suicide is one of the greatest sins. Allah Almighty forbade Muslims to commit crimes not only against others, but against himself. He forbade man to suicide and all that can cause a person to death.
Allah said in the Quran: “Do not kill yourselves [or one another]. Indeed, Allah is to you ever Merciful”. (The Quran, 4:29)
The Messenger of Allah (peace be upon him), on this occasion said: “Let not any one of you wants death himself! And let no one prays to Allah to death before its arrival. For, indeed, if you die, your deeds and actions are completed on this, but life (despite its ease or difficulty) carries the believer only benefit”. (Hadith narrated by Abu Huraira, in collections of Ahmad and Muslim).
Psychologists subdivide all suicides into two classes: the true and demonstrative. The true is, as a rule, well-planned, deliberate action, the purpose of which any cost to lose life, regardless of the opinions and reactions of relatives, friends, etc. Demonstrative is not so much an attempt to kill himself, as a “cry for help”, an attempt to make himself and his problems the attention of others and is committed in a state of affect.
If a person lost his composure and came into total despair, in the very difficult for a person the moment of close relatives shall take measures: a helping hand, to convince him that he is needed. But often few people take seriously the experience a desperate man, until it will not lead to irreversible consequences.
Islam prohibits all kinds of violence against anyone, including on himself. At the same time, Islam aims to support people in the difficult moments of life. Sincere believer knows that any tragedy, be it the loss of a loved one, a serious illness or a collapse in his career - it's just a test, followed by a release, either in this life or the next. How sincere people will tolerate his burden, hoping for mercy and relief from the Almighty, so happy and will be the outcome of his patience.
The Creator of all things has given man life and only He has the right to take it away. The Almighty said in the Quran (the meaning): “Do not push yourself to death!” Surah Al-Baqarah, verse 195.
The Prophet Muhammad (peace be upon him) said: “If someone throws himself off a mountain and kills himself, in the Fire of Hell he will be throwing himself down forever. If someone drinks poison and kills himself, in the Fire of Hell he will have his poison in his hand which he will drink forever. If someone kills himself with iron, in the Fire of Hell he will have his iron weapon in his hand stabbing his belly with it forever” (narrated in the book “Sahih Bukhari”, 5442).
Accordingly, a suicide or infliction of harm to own health are the gravest sins before the Creator. While it is said in the above hadith that suicide would be subjected to torture forever, Hadith commentators believe that the Messenger of Allah (peace be upon him) meant a long period and not forever (because no Muslim will burn in Hell forever).
As for the burial of a suicide, that in the opinion of Imam Abu Hanifa and Muhammad al-Shaybani (may Allah be pleased with them), then it is read - Janazah prayer, as well as being done for him “du’a”.
Among suicide can also be considered and suicide bombers, with one exception – to the sin of suicide in this case added to the sin of murder. After all, these people take away not only their life but also the lives of many innocent people. In addition, these people generate contempt towards Islam by others.
