On earth we get one percent of God's mercy and when we die we get the other 99 percent. My husband always said, "Never be afraid to die, as Allah is so merciful and forgiving.".
It is a waste of time to worry about the dead as their fate is decided. Two things that save a dead person.
1. A good son praying for him.
2. A everlasting charity such as money spent on a book or church or mosque.
My grandfather died and I had a dream later as my mom was crying all the time. He told me that he would not come back ever to the earth even if he was paid. I think many thousands have had the same dream. The afterlife is what we should be working for, this life is a test only.
