Assalamualaykum. Physical pain, its a secret :P cannot discuss in public. I know its so sad.
I think thats the worse pain there could be. Insha'Allah Allah will protect us from the pain of dying. The person dying looks to his left and right and sees Angels everywhere.
The Angels of Mercy come to a Muslim and for the Kaafirs, the Angels of Punishment appear. At this time, even the Kaafirs believe the truth about Islam, but their faith at this time is not counted. This is because faith is the name of believing the Message of Allah Ta'ala and his beloved Messenger (sallal laahu alaihi wasallam) without seeing proof.
At this time one sees the Angels and then believes and this is therefore, not accepted as a Muslim. A Muslim's soul is taken out with ease and is then taken with respect by the Angels of Mercy. A Kaafir's soul is taken out with great pain and the Angels of Punishment take it with disgrace.
Omg the worst physical pain was standing on a plug while not wearing any socks poor kuffar.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
