Al-'Afuww
Allah is Al-Afuw, The One who pardons sins and leaves no trace of any fault. He also pardons evil intentions if they do no materialize.
From the root ‘a-f-a which has the following classical Arabic connotations: to forgive, pardon to pass over, forgo, absolve to obliterate all traces, efface, remove to kill-off, allow to die to turn away from punishing, not see, annul to make unapparent, imperceptible to give spontaneously, to give without constraint to give more than what is due
Those who pronounce thihar among you [to separate] from their wives – they are not [consequently] their mothers. Their mothers are none but those who gave birth to them. And indeed, they are saying an objectionable statement and a falsehood. But indeed, Allah is Pardoning and Forgiving. (Quran 58:2)
That [is so]. And whoever responds [to injustice] with the equivalent of that with which he was harmed and then is tyrannized – Allah will surely aid him. Indeed, Allah is Pardoning and Forgiving. (Quran 22:60)
If [instead] you show [some] good or conceal it or pardon an offense – indeed, Allah is ever Pardoning and Competent.(Quran 4:149)
For those it is expected that Allah will pardon them, and Allah is ever Pardoning and Forgiving. (Quran 4:99)
