Messenger of Allah said, ‘Allah Almighty says, “O son of Adam! I will forgive you as long as you call on Me and have hope in Me, no matter what you do.
Son of Adam, I do not care if your wrong actions reach to the clouds of heaven and then you ask Me for forgiveness, I will forgive you.
Son of Adam, if you were to come with sins equivalent in weight to the whole earth and then meet Me having not associated anything with Me, I would come to you with the same amount of forgiveness.'” [at-Tirmidhi]
