`O son of Adam! I shall go on forgiving you so long as you pray to Me and aspire for My forgiveness whatever may be your sins.
O son of Adam! I do not care even if your sins should pile up to the sky and should you beg pardon of Me, I would forgive you.
O son of Adam! If you come to Me with an earthful of sins and meet Me, not associating anything with Me in worship, I will certainly grant you as much pardon as will fill the earth.”
[At-Tirmidhi Hadith # 3540].
