An-Nisa' - 4:99

فَأُوْلَـئِكَ عَسَى اللّهُ أَن يَعْفُوَ عَنْهُمْ وَكَانَ اللّهُ عَفُوًّا غَفُورًا
[4:99]
So these, it may be, Allah will pardon them, and Allah is Pardoning, Forgiving.
For these, there is hope that Allah will forgive: For Allah doth blot out (sins) and forgive again and again.
As for such, it may be that Allah will pardon them. Allah is ever Clement, Forgiving.
