Islamic Beliefs Life After Death

What are the strengths and weaknesses of the Islamic belief on the afterlife?

I need to know the strengths and weaknesses of their belief on life after death. ALSO PLEASE CAN YOU TELL ME, IF YOU CAN, SOME EVIDENCE THAT BACKS UP THE ISLAMIC VIEW ON THE AFTERLIFE.

Thanks if you can xx

The weakness is that God is in the 7th level of heaven and people are on the other 6. How great is heaven if God is isolated. May as well stay here on earth. Also they do not believe in Jesus as God, and since He is the only way of redemption, they have none.
