8. Avoid the seven noxious things.(1) Associating anything with Allah, (2) magic, (3) killing one whom Allah has declared inviolate without a just cause, (4) devouring usury, (5) consuming the property of an orphan, running back from the battlefield and, (7) slandering chaste women who are believers but indiscreet.
(Bukhari, Muslim).
