Praise be to Allah, Lord of the Worlds, and prayers and peace be upon the prophet as a mercy to the worlds and on his family and companions. The phenomenon of suicide is one of the most expanding social phenomena in the world, where many groups of society of different ages try to put an end to their lives, especially young men and girls. The numbers always remain on the rise, and there is no doubt that the one who does this matter, that he has reasons that made him resort to suicide, and despite that, whatever those reasons. However, this is not a justification for the assault on the soul that God has forbidden to infringe on or lead them to perdition, or to what harms them. Modern psychology has tried to explain this phenomenon and try to reach the reasons that push a person to take the end of his life by himself and among the reasons driving this crime psychological reasons and most contemporary psychologists believe that psychological reasons remain one of the most prominent reasons driving suicide when people suffer mental illness and psychological pressure, they do not hesitate to commit suicide and that is only because of the absence of scruples and religious deterrent. The believers in the judgment of God and their ability to find them receive the misfortunes of the world with the same satisfaction reassuring. So it was necessary to activate the role of faith to address this dangerous phenomenon The Holy Quran has mentioned a lot of self-medicine and prescribed her effective treatment which is described as healing for people. The Holy Quran has treated diseases that would be the cause of the destruction of the individual and the group, and cared greatly in people's lives, and vowed to demolish the lives of others severe torment, and ordered the same person to maintain life, whether through the prevention of diseases, or through medication. Hence there is an urgent need to identify the causes, and then initiate the development of treatment all this within the framework of the Koran so I gave this research the title psychological causes of suicide in the Holy Quran.
