Dear Ustadh can explain briefly how to use تورية and its permissibility احسن الله إليكم

Tawriyah, also called al-ma'arid (equivocation), is to say something whose apparent wording carries one meaning while you intend by it a second, true meaning that the words genuinely bear, even if the listener understands the first. This is used only when there is a real need for it, for example, to avoid a greater evil.
