It is narrated from Hazrat Mahmood bin Labeed (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: "What I fear most for you is minor shirk." The people asked, "O Messenger of Allah! What is meant by minor shirk?" The Noble Prophet (peace and blessings be upon him) said: "Showing off (riya)." Allah Almighty will say to the show-offs on the Day of Judgment, "When people are being rewarded for their deeds, go to those for whom you used to perform deeds to be seen by them in the world, and see if you find any reward with them."
