People may have different answers to these questions. Many reasons why you might not be, and some people are afraid.
Mine is the one who is afraid of the coming death. The thing that I am scared of most is the sickness of dying. In Islamic belief, though from the outside, one’s dying did not look sick, but in real he suffered. The lightest sickness of dying is like a goat was skinned alive.
Life after death also scared me. I am not sure whether this was the trauma I brought from childhood when my teachers told me scary things about the punishment for sinful people. Or, I am indeed a weak human.
I blamed the exaggerated lessons the teacher gave us in the past. That no one can pass the punishment in the grave. Even good people have to pay for the mistakes he made during his life, though only a tiny fault.
It seems that the good things humans do in the world can not cover their sins, although they try to do their best and ask for forgiveness every day.
After I grew old, I tried to neutralize the feeling of death scary. I believe in the mercy of God. He must understand when I did wrong. Perhaps not all was my mistake. Several external factors influenced me, and may He forgive me for that.
Years of my childhood under extreme teaching about life after death can not be neutralized by a short time of wise teachings. Yet, I am grateful that on one occasion, one of the famous ulama said this.
No need to fear death. Consider how you felt when you were tired and finally allowed to sleep—you must be happy. That is akin to death. You should not be worried or afraid. Because from that moment on, you are liberated from the burdens of this world.
This is a small light in the darkness of my perspective on death.
