Full Sharh — Riyad as-Salihin 1199
وعن أنس رضي الله عنه قال: سمعت رسول الله صلى الله عليه وسلم يقول: “قال الله تعالى: يا ابن آدم إنك ما دعوتني ورجوتني غفرت لك ما كان منك ولا أبالي، يا ابن آدم لو بلغت ذنوبك عنان السماء، ثم استغفرتني ، غفرت لك ولا أبالي، يا ابن آدم إنك لو أتيتني بقراب الأرض خطايا، ثم لقيتني لا تشرك بي شيئاً، لأتيتك بقرابها مغفرة" . (2)
English Translation
Anas (May Allah be pleased with him) said:: I heard the Messenger of Allah (ﷺ) 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."'.
