What is the Islamic response for those who wish they were not born into this existence, who wish they were not part of the world in this life or the next and want neither the punishment nor the reward?
Bismillah
Thank you for your question. It is God who decides who exists and that is not the choice of an individual. What is in their choice is what they do with the life they are given, and not wanting life, reward or punishment is not something that absolves them from that responsibility.
May you always be successful
