Mustahabb

Mustahabb is a term used in Islamic jurisprudence to describe actions that are recommended or desirable. An act labeled mustahabb is praised and rewarded if performed, but it is not obligatory. The opposite categories include fard or wajib (obligatory) and makruh (disliked). Thus, mustahabb sits in the realm of encouragement rather than compulsion.

Etymologically, mustahabb derives from the Arabic root istahabb, meaning to deem something desirable or worthy of reward. In legal texts, it denotes acts that improve one’s character, spirituality, or social conduct without imposing a duty on the individual.

In fiqh, acts are classified into several categories: fard (obligatory), wajib (also obligatory in some schools), sunnah (recommended practice, including sunnah mu’akkadah and sunnah ghair mu’akkadah), mustahabb (recommended), and makruh (disliked). Mustahabb acts are those the believer is encouraged to perform to gain spiritual reward, but their omission does not incur sin in the same way as omitting a fard act. Some scholars note that combining mustahabb acts with obligatory duties can enhance reward.

Examples of mustahabb acts include voluntary prayers (nafl), fasting on non-obligatory days (such as Mondays and Thursdays or the white days), extra charitable giving beyond obligatory zakat, visiting the sick, keeping good relations with family and neighbors, and reciting the Qur’an or Dhikr beyond what is required. The status of specific actions as mustahabb can vary slightly between madhhabs, reflecting differing jurisprudential assessments.

In practice, mustahabb serves to guide believers toward virtuous behavior without imposing legal penalties for non-compliance, while offering potential spiritual reward for those who choose to perform them.
