The Cow - 2:109
Many of the People of the Book desire, out of jealousy in their hearts, to turn you back to disbelief after your faith, even though the truth is clear to them. Forgive them and ignore them until Allah brings His command. Allah is all-powerful.
If we forgive an evil:
Council/42:40
The recompense for evil is a like evil, but whoever forgives and acts righteously will be rewarded by Allah. He does not love the wrongdoers.
The Heights/7:199
Be forgiving, preach tolerance and pay no heed to the ignorant.
Council/42:37
Those who avoid the great sins and the ugly deeds and forgive when they are angry.
The Women/4:149
And if you reveal or conceal a good deed, or forgive an evil deed, Allah is Forgiving, Powerful.
The Table Spread/5:45
There We commanded them: We commanded them: Life for life, eye for eye, nose for nose, ear for ear, tooth for tooth and wounds for wounds. Whoever gives up this right, He will cover his sins. Those who do not judge by what Allah has revealed are wrongdoers.
