“Allah the Most High says: ‘O son of Adam! As long as you supplicate to Me and hope in Me, I will forgive you what you have done. O son of Adam! If your sins were to reach the lofty regions of the sky, then you ask Me for forgiveness, I would forgive you. O son of Adam! If you were to come to Me with enough sins to fill the earth, but you met Me not associating anything with Me I would bring you the like of it of forgiveness.”

[Sahih al-Bukhari, vol: 8, no: 319]
