Forbidden oaths are those sworn by al-Lฤt, al-โUzzฤ, false gods, or anything worshipped besides Allah Most High. Swearing by something entails venerating it, and venerating these things constitutes disbelief in Allah Most High.
Section
Binding oaths that require expiation if broken, unless the swearer makes an exception, are those concerning future matters, such as saying, โBy Allah, I will not do it,โ or โBy Allah, I will certainly do it.โ Oaths concerning the past require no expiation, whether a person swears to something he knows to be true, to something he believes certain but which proves otherwise, deliberately to a falsehood, or to something about which he is uncertain.

The first, which is the best-known, takes account of the circumstances and peopleโs purposes in swearing oaths. According to this opinion, an oath is interpreted according to the swearerโs intention. If he had no particular intention, it is interpreted according to the circumstances surrounding his oath. If he had neither a particular intention nor circumstances underlying his oath, it is interpreted according to peopleโs customary purposes in swearing oaths. If no customary purpose is known in the matter, his oath is understood according to the apparent meaning of his words in their literal linguistic sense. If the wording admits two or more interpretations, the most apparent is adopted. If neither is more apparent than
