It is narrated from Hazrat Abu Dharr Ghifari (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Allah Almighty says, "O My servant! However much you worship Me and place your hope in Me, I will forgive all your sins. O My servant! If you come to Me with sins as much as the earth but do not associate anyone with Me, I will meet you with as much forgiveness, and it will not matter to Me." ... Then the narrator mentioned the entire hadith.
