Muslims are meant to believe that god is just, that he is fair but why does Allah kill some people when they are just a child/baby, they die without any sin. or why does he make some people insane and they too are not accountable for anything all of these people die without any sin, but others have to believe in Allah, pray, fast and do other things just so they can enter heaven. Why does Allah do this? If Allah killed me when I was a baby or if he made me insane then I too would my sin be forgiven like them, why does he help these people in this way? How is this fair?
