It is narrated from Hazrat Abu Saeed Khudri (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: On the Day of Resurrection, Allah Almighty will ask the servant, "When you saw a sinful act being committed, why did you not stop it?" Then the one to whom Allah grants an argument will say, "O Lord! I hoped for Your forgiveness but I was afraid of the people."
