The Arabic term for permissible actions in Islam is:

The Arabic term for permissible actions in Islam is Halal. In Islamic jurisprudence (fiqh), halal refers to anything that is lawful and permitted under Islamic law. It applies broadly to food, drink, financial transactions, personal conduct, and any other aspect of life.

Islamic law classifies all human actions into five categories (al-ahkam al-khamsah):

• Wajib/Fard - obligatory (rewarded if done, sinful if omitted)
• Mustahab/Mandub - recommended (rewarded if done, no sin if omitted)
• Mubah/Halal - permissible (no reward or sin either way)
• Makruh - disliked (better to avoid, but no sin if done)
• Haram - prohibited (sinful if done, rewarded if avoided)

Among the options listed, Haram is the direct opposite of Halal, meaning what is forbidden. Mustahab refers to recommended acts that are more than merely permissible. Sunnah refers to the practice of Prophet Muhammad and, in jurisprudential usage, overlaps with recommended acts. The term that specifically denotes general permissibility is Halal.
