What it means
مستحب (mostahabb) derives from the Arabic root h-b-b, meaning “to love” or “to be beloved,” with the مستـ prefix forming a pattern of seeking or being in a state of something. In Islamic jurisprudence it names acts that are encouraged and rewarded but not compulsory. A person who performs a مستحب act earns spiritual merit (ثواب), but someone who skips it commits no sin. It sits just below واجب in the five-category ranking and is often contrasted with مکروه (discouraged). Common synonyms in Arabic-Persian religious discourse are سنّت (sonnat) and نافله (nâfele).
How to use it
- نماز شب مستحبه، ولی واجب نیست. (Namâz-e shab mostahabbe, vali vâjeb nist.) “The night prayer is mostahab, but not obligatory.”
- غسل جمعه مستحبه. (Ghosl-e jom’e mostahabbe.) “The Friday ritual bath is mostahab.”
- این دعا رو بعد از نماز بخون، مستحبه. (In do’â ro ba’d az namâz bekhun, mostahabbe.) “Recite this supplication after prayer, it is mostahab.”
- خیلی از کارهای مستحب توی رساله نوشته شده. (Khili az kârhâ-ye mostahab tu-ye resâle neveshte shode.) “Many mostahab acts are written in the resâle.”
Cultural note
Mostahab acts form a large and varied category in Shia practice, covering additional prayers, particular supplications, charitable acts, and etiquette around eating, sleeping, and entering a home. Because they are rewarded but not compelled, they represent the voluntary spiritual life a believer builds beyond the obligatory minimum. In practice, many devout Iranians are as attentive to well-known mostahab acts as they are to واجب duties, viewing them as a way to draw closer to God. The category is also important in Sufi and mystical traditions, where voluntary devotion beyond the law is valued highly.
