Categories of Islamic Rulings (Ahkam al-Khamsah)

Overview

Islamic jurisprudence classifies every human action into one of five categories (al-ahkam al-khamsah). These categories provide a comprehensive framework for understanding what is required, recommended, permitted, disliked, or forbidden in Islam.

The Five Categories

1. Fard / Wajib (Obligatory): Actions that are mandatory. Performing them is rewarded, and abandoning them without excuse is sinful. Examples: the five daily prayers, fasting Ramadan, zakat. The Hanafi school distinguishes between fard (established by definitive evidence) and wajib (established by probable evidence), while the other schools treat them as synonymous.

2. Mustahabb / Mandub / Sunnah (Recommended): Actions that are encouraged but not mandatory. Performing them is rewarded, but omitting them is not sinful. Examples: praying the Sunnah prayers (rawatib), fasting on Mondays and Thursdays, using the siwak.

3. Mubah (Permissible): Actions that are neither rewarded nor punished. A person has complete freedom in these matters. Examples: choosing what permissible food to eat, which permissible clothing to wear. An action that is mubah can become rewarded if done with a good intention.

4. Makruh (Disliked): Actions that are discouraged but not sinful. Avoiding them is rewarded. The Hanafi school distinguishes between makruh tahrimiyan (closer to haram) and makruh tanzihi (mildly disliked). Examples: wasting water in wudu, praying in a graveyard (in some schools).

5. Haram (Forbidden): Actions that are absolutely prohibited. Committing them is sinful, and avoiding them is rewarded. Examples: consuming alcohol, eating pork, murder, theft, fornication, interest (riba).
