Does a Muslim have to abstain from drug use, such as cocaine, in order to embrace Islam?

Your consideration of embracing Islam given your current circumstances is a great and astonishing matter, indicating a desire for guidance that God alone can bestow. Indeed, the heart of an unbeliever is dead until God revives it with the light of Islam, as He states: (Is he who was dead and We gave him life and made for him a light by which he walks among the people like one who is in darknesses, never to emerge therefrom?). As for drugs, the religion of Islam prohibits everything harmful and permits everything beneficial. It forbids everything that clouds the mind and leads to corruption, for drugs corrupt religion, the soul, the mind, honor, and wealth. Our understanding of the difficulty of addiction does not preclude one from entering Islam; rather, your embracing it will generate within you a strength and will that will aid you in overcoming addiction. This may take time, but that should not prevent you from entering Islam.
