1. Fard/Wajib — Obligatory
Definition: An act whose performance is required and whose omission is a sin.
Evidence level: For the Shafi’i, Maliki, and Hanbali schools, fard and wajib are synonyms. For the Hanafi school:
- Fard: Established by qat’i (definitive) evidence — Quran text or mutawatir (mass-transmitted) hadith
- Wajib: Established by zanni (probable) evidence — ahad (solitary) hadith; still obligatory but at a lower certainty level
Examples of Fard:
- The five daily prayers (fard ‘ayn — obligatory on every individual)
- Fasting in Ramadan
- Zakat (for those who meet the nisab)
- Hajj (once in a lifetime, for those able)
- Believing in the six pillars of iman
Examples of Wajib (Hanafi specific):
- The witr prayer
- Saying “Ameen” after Fatiha in prayer
Subdivisions:
- Fard ‘ayn: Obligatory on every individual (prayer, fasting)
- Fard kifaya: Collective obligation — if a sufficient number of the community performs it, the rest are absolved; if no one does, all are sinful (e.g., responding to the Islamic greeting, attending to the dead — ghusl, janazah prayer, burial)
2. Mandub/Mustahabb/Sunnah — Recommended
Definition: An act whose performance is rewarded but whose omission incurs no sin.
The three terms:
- Mandub: Recommended (general term)
- Mustahabb: Beloved/desired (emphasizes the divine preference)
- Sunnah: The prophetic way (emphasizes its connection to the Prophet’s practice)
Subdivisions:
- Sunnah mu’akkada: Emphasized Sunnah — the Prophet (SAW) consistently performed it and rarely or never omitted it. Omitting it is not sinful but is blameworthy. Examples: the 2 rak’at before Fajr, the 4 rak’at before Zuhr, the witr prayer (non-Hanafi), praying in congregation
- Sunnah ghair mu’akkada: Non-emphasized Sunnah — the Prophet (SAW) sometimes did and sometimes omitted. Examples: additional voluntary prayers, fasting Mondays and Thursdays
Examples:
- Greeting with salam upon entering the home
- Miswak (tooth-stick) before prayer
- Praying 2 rak’at tahiyyat al-masjid upon entering the mosque
- Fasting 6 days of Shawwal
3. Mubah — Permitted/Neutral
Definition: An act that is neither commanded nor prohibited — indifferent; no reward for doing it and no sin for doing it (or omitting it).
The enormous scope of mubah: The Quran establishes that the default for all things is permissibility: “It is He who created for you all of that which is on the earth.” (2:29) — Things are permitted unless specifically prohibited. Most of human life falls in the mubah category: eating, drinking (non-intoxicant), sleeping, most social interaction, business, leisure.
Examples:
- Eating any halal food
- Choosing what color to wear
- Which hand to carry something with
- Most forms of recreation and entertainment
The principle of minimal rulings: Islamic law does not regulate every human action — the mubah sphere is intentionally vast, representing the freedom of human agency within divine bounds.
4. Makruh — Disliked
Definition: An act that is discouraged — rewarded if avoided, but no sin if done.
Subdivisions:
- Makruh tahrimi (Hanafi): Close to prohibited — almost sinful. The evidence for prohibition is probable rather than definitive. Examples: wearing gold for men (some Hanafi scholars), eating with the left hand
- Makruh tanzeehi: Mildly discouraged — below the level of near-prohibition. Examples: wearing certain colors in prayer (school-specific), excessive eating (not to the level of harm)
Examples:
- Eating with the left hand (though the right is Sunnah, the left is makruh not haram)
- Selling things in the mosque
- Speaking unnecessarily between the adhan and iqama
- Excessive laughter
- Sleeping after Fajr and before Ishraq
5. Haram — Prohibited
Definition: An act whose commission is sinful — doing it incurs punishment from Allah (unless repented from); in many cases, Islamic law also provides worldly sanctions (hudud, ta’zir).
Evidence level: Must be established by definitive evidence (Quran or mutawatir hadith) in the Shafi’i/Maliki/Hanbali view. In Hanafi: strong ahad hadith can establish haram.
Categories:
- Haram li-dhatihi (prohibited for its intrinsic nature): Alcohol, pork, adultery, murder — the thing itself is the harm
- Haram li-ghayrihi (prohibited for an external reason): An otherwise permissible act that becomes haram due to context — selling halal food on Jumu’a during the prayer time (2:9 — prohibited due to its interfering with the obligation); performing a valid sale contract with a prohibited clause
Examples:
- Consuming alcohol, pork, and blood
- Riba (interest)
- Adultery and fornication
- Murder
- Theft
- Lying and false testimony
