Is suicide permissible out of fear of the sins and transgressions with which one has been afflicted, despite repeated attempts at repentance and failure to desist from them?

It is not permissible to take one's life under the pretext of falling into sin and being unable to desist from it. Suicide is a transition to great misery and torment, and it is forbidden and considered one of the major sins. Allah Almighty says: "And do not kill yourselves. Indeed, Allah is ever Merciful to you" (Quran 4:29). The Prophet, peace and blessings be upon him, clarified the torment of one who kills himself. Whoever is afflicted by sin must fear Allah and supplicate to Him to grant them success in repentance, and they should strive to abandon the corrupt environment.
