Whose repentance is accepted?

Allâh accepts only the repentance of those who do evil in ignorance and foolishness and repent soon afterwards; it is they whom Allâh will forgive and Allâh is Ever All¬Knower, All¬Wise.

And of no effect is the repentance of those who continue to do evil deeds until death faces one of them and he says: "Now I repent;" nor of those who die while they are disbelievers. For them We have prepared a painful torment.

An-Nisa 17-18
