Reading this book "The Spectacle of Death: Including Glimpses of Life Beyone the Grave" Every Soul Must Taste Death by K.M. Islam
It is said that when Moses (peace be upon him) died, Almight God asked him how did he feel the agonies of death. He replied that it seemed to him as if an alive sparrow was being roasted in such a way that its sould lingered in the body and it found no way to escape. He is also reported to have said that his condition was just like an alive goat which was being flayed.
It's better to not prefer death or life but to please Allah.
I remember when i told my friend when I was going to become Muslim he said don't take it lightly it takes you on a long twisted trip. Allah u Akbar.
and in the book it said we should remember death 20 times a day so we humble ourselves and accept death. One who reminds himself of death frequently, his heart become alive and death becomes easy for him.
Salaam Alaikum
