Narrated ‘Ali reported that God’s messenger said, “A man is not a believer till he believes in four things:
he must testify that there is no god but God and that I am God’s messenger whom He sent with the truth ; he must believe in death and in the resurrection after death; and he must believe in the divine decree."
I heard God’s messenger say, “Some of my people will be swallowed up and some will be metamorphosed. That will come about among those who declare God’s decree to be false."
Abu Dawud transmitted it and Tirmidhi transmitted something similar.
