What is the ruling on lying to someone whose lies you have grown weary of, such as claiming to have changed your phone number or that you do not have internet access, when that is not true?

Lying is forbidden, and it leads to immorality. Therefore, it is not permissible to resort to it to get rid of those who frequently lie. Lying can be avoided by resorting to tawriya (equivocation) and ma'arid (allusions), because they provide a way out of lying. Tawriya and ta'rid involve uttering a word that appears to mean one thing, but intending another meaning that the word can encompass, though it is contrary to its apparent sense. If there is a prevailing legitimate Islamic benefit or a pressing need that cannot be avoided except through lying, then there is no harm in them. Otherwise, they are disliked, unless they are used to seize something false or deny a right, in which case they become forbidden.
