The Messenger of Allah (may Allah's peace and blessings be upon him) commands his Ummah to shun seven ruinous crimes and sins. When asked about them, he outlined them as the following: First: associating partners with Allah by taking anyone or anything as a peer and equal to Him and by devoting any act of worship to other than Allah Almighty. He began with polytheism because it is the gravest sin. Second: magic, which includes knots, incantations, treatments, and making smoke, affects the bewitched person's body, causing him to die or fall ill, or it causes separation between husband and wife. It is the work of the devil and mostly cannot be performed except through polytheism and pleasing the evil spirits by doing any of the things they like. Third: killing a person whose killing Allah has prohibited except by a legal cause implemented by the ruler. Fourth: consuming usury by taking it or any other form of benefit. Fifth: encroaching upon the property of a child whose father died before he reaches puberty. Sixth: fleeing the battle with the disbelievers. Seventh: accusing chaste and noble women of adultery, as well as accusing men.
