[5:80] You would see many of them allying themselves with those who disbelieve. Miserable indeed is what their hands have sent forth on behalf of their souls. GOD is angry with them and, consequently, they will abide forever in retribution.
[5:81] Had they believed in GOD, and the prophet, and in what was revealed to him herein, they would not have befriended them. But many of them are evil.
