المعنى الاصطلاحي :

The most likely place where something could exist.

الشرح المختصر :

"Mazhinnah" (most likely place/situation) is the place/situation where something could most likely exist/occur. For example, sleeping is a likely situation for breaking wind, and puberty is a likely age for maturity. It is notable, however, that this likelihood is not subject to independent reason or authority. It is, rather, determined by textual proof from the Qur’an, the Sunnah, or consensus.

التعريف اللغوي المختصر :

"Mazhinnah": object of assumption. If it is coupled with something, it means the most likely place/situation where that thing exists. Derived from "zhann", which means doubt and hesitation; opposite: "yaqeen" (certainty), and it can also be used to mean certainty and knowledge.
