Hadrat Anas ibn Malik (r.a.) said: ‘I heard the Messenger of Allah (saws) saying, “Allah, the Exalted, has Said: ‘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.”’Related by At-Tirmidhi.
