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.
What is true?
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.
The Apartments/49:7
Know that the Messenger of Allah is among you. Had he followed you in most of the affairs, you would have been in distress. But Allah has endeared to you the faith and adorned it in your hearts, and He has made disbelief, evil and rebellion ugly to you. These are they who follow the truth.
The Cattle/6:82
Those who believe and do not mix their faith with wrongdoing, they deserve security and they have found the truth.
The Heights/7:178
Whomever Allah guides to the truth, it is he who finds the truth. And whomsoever He leads astray, they are the losers.
The Family Of Imran/3:20
"If they dispute with you, say, "I and those who follow me have submitted ourselves to Allah."Say to those who have been given the Book and those who have not been given the Book, "Have you submitted?"If they submit, they will find the truth. If they turn away, your duty is only to announce. Allah sees the servants."
The Night Journey/17:97
Whomever Allah guides, he has found the truth. And whomsoever He leads astray, you will find for them no protector except Him. On the Day of Resurrection We will gather them together, blind, dumb and deaf. Their abode will be Hell. We increase its flames as it cools.
The Cave/18:17
When dawn came, while they were in the cave, you used to see the sun moving to the right over their cave, and when it set, you used to see it licking them and sliding to the left. This is one of the signs of Allah. Whomsoever Allah guides, he has found the truth; and whomsoever He leads astray, for him you will not find a friend who will enlighten.
The Family Of Imran/3:51
"Allah is my Lord and your Lord; serve Him. This is the right way."
