The Spoils of War - 8:29
O you who believe, if you listen to Allah, He will give you understanding to distinguish right from wrong, and He will cover your evil deeds and forgive you. Allah is the Owner of Great Grace.
Wrong:
Luqman/31:30
For Allah is the Truth, and what they call besides Him is falsehood, and Allah is the Most High and the Greatest.
The Women/4:51
"Do you not see those who have been given a share of the Book? They believe in idolatry and false doctrines, and say of those who disbelieve, "These are more rightly guided than those who believe"."
The Cow/2:256
There is no compulsion in religion. So the truth is separated from error. Whoever disbelieves in Taghut (despots and evil doctrines) and believes in Allah, he has clung to an unbreakable and firm bond. Allah Hears, Knows.
