O ye who believe! if ye fear Allah, He will grant you a Criterion(1202) (to judge between right and wrong), remove from you (all) evil (that may afflict) you, and forgive you: for Allah is the Lord of grace unbounded.
1202 Cf. 2:53 and 2:185. The battle of Badr is called the Furqan in Muslim theology, because it was he first trial of strength by battle, in Islam, between the powers of good and evil. Evil was defeated, and hose who had real faith were tested and sorted out from those who had not faith enough to follow the banner of Faith. See also 8:41 and n. 1210.
