That which is lawful is plain and that which is unlawful is plain and between the two if them are doubtful matters about which not many people know. Thus he who avoids doubtful matters clears himself in regard to his religion and his honour, but he who falls into doubtful matters falls into that which is unlawful, like the shepherd who pastures around the sanctuary, all but grazing therein. Truly every king has a sanctuary, and truly Allah's sanctuary is His prohibitions. Truly in the body there is a morsel of flesh which, if diseased, all of it is diseased. Truly it is the heart.
Avoid the seven noxious things. (1) Associating anything with God, (2) magic, (3) killing one whom God 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.
If you guarantee me six things on your part, I shall guarantee you paradise: speak the truth when you talk, keep a promise when you make it, when you are trusted with something fulfill your trust, avoid sexual immorality, lower your eyes and restrain your hand from injustice.
