Sayyiduna Abu Dharr (may Allah be pleased with him) reports that (on one occasion) the Messenger of Allah (peace and blessings be upon him) said: "A messenger came to me from my Lord and informed me—or he said: gave me glad tidings—that whoever from my Ummah dies in a state that he does not associate anything with Allah, he will enter Paradise." I asked, "Even if he has committed adultery and even if he has stolen?" The Prophet (peace and blessings be upon him) replied: "Even if he has committed adultery, even if he has stolen."
