Mubāḥ (Arabic: مباح) is an Arabic word roughly meaning "permitted",[1] which has technical uses in Islamic law.
In uṣūl al-fiqh (principles of Islamic jurisprudence), mubāḥ is one of the five degrees of approval (ahkam):
Mubah is commonly translated as "neutral" or "permitted" in English.,[2][3] "indifferent"[4] or "(merely) permitted".[4][5] It refers to an action that is not mandatory, recommended, reprehensible or forbidden, and thus involves no judgement from God.[2] Assigning acts to this legal category reflects a deliberate choice rather than an oversight on the part of jurists.[3]
In Islamic property law, the term mubāḥ refers to things which have no owner. It is similar to the concept res nullius used in Roman law and common law.[6]
