Hadith 1011
Sayyiduna Thawban, may Allah be pleased with him, who was a servant of the Prophet (peace and blessings be upon him), reports that the Prophet (peace and blessings be upon him) said: "I do not wish for people from my Ummah who will come on the Day of Resurrection with good deeds like the mountains of Tihamah, and Allah Almighty will make those good deeds scattered dust." The Companions said: O Messenger of Allah! Tell us who they are, so that we do not become like them while we do not know? He (peace and blessings be upon him) said: "They are from among your brothers, they are such people that when they are alone, they commit what Allah has forbidden."
