How can it be just that I am forced to live and cannot end my life, knowing that "there shall be no compulsion in religion," yet my doing so would lead me to Hellfire?

Whoever believes that Allah created them and commanded and forbade them, and knows that suicide is an evil end and a punishment, must not object to Allah's command and action. For objecting to Allah in His creation is a greater sin than suicide. Allah creates what He wills and chooses, and the created being has no choice in their creation and existence. Allah created jinn and humans for His worship. A Muslim must be wary of following Satan in his objection to the creation of Adam (peace be upon him) and his refusal to prostrate to him. If a Muslim were to do what Allah commanded and then ask about the wisdom of their creation, it would be acceptable. However, objecting to His cosmic will and disobeying His legislative commands is a serious matter. As for His (the Almighty’s) saying: (There is no compulsion in religion), it has no relation to the issue of compelling creation to exist. This verse pertains to religious rulings and not to compelling people to embrace Islam. And He (Allah) is not questioned about what He does, but they will be questioned.
