just saying that in islam, suicide is a major sin.in a nutshell, the reason is that he chooses to abandon all of his responsibilities and gave up on his faith that God knows what hes doing by testing him and that God is capable and will help his servants. rage quitting wont solve anything and will aggravate the situation. we are given the blessing of life that needs to be taken care of. our souls belong to him. not ourselves.
Brother why are you wasting your time on useless nonsense when you should be focusing on you aakhira. Once you let go of the chains of dunya, you will be able to spend more time usefully in the name of Allah.
