Al-A'raf 7:153

Wallatheena AAamiloo assayyi-atithumma taboo min baAAdiha waamanoo innarabbaka min baAAdiha laghafoorun raheem

But those who committed misdeeds and then repented after them and believed - indeed your Lord, thereafter, is Forgiving and Merciful.

As for those who do evil, and repent thereafter, and embrace faith, your Lord is then most forgiving, very merciful (for them).
