It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The people who will receive the severest punishment on the Day of Resurrection are: a man who killed a prophet, or whom a prophet killed, or a man who misguides people without knowledge, or an image-maker who makes statues."
