Mustahabb () or Mandub () is an Islamic term referring to an action or thing that is recommended and favoured.
Mustahabb actions are those whose ruling (ahkam) in Islamic law falls between mubah (neutral; neither encouraged nor discouraged) and wajib (compulsory). One definition is "duties recommended, but not essential; fulfilment of which is rewarded, though they may be neglected without punishment".Reuben Levy, The Social Structure of Islam, p. 202 Synonyms of mustahabb include masnun and mandub. The opposite of mustahabb is makruh (discouraged).
Parallels have been drawn between the concept of mustahabb in Islamic law and the concept of supererogatory acts in the Western philosophical tradition.
Ahkam
Examples There are possibly thousands of mustahabb acts, including:
Sadaqah (charity outside of zakat) Saying As-salamu alaykum Umrah (except in the Shafi'i and Hanbali madhhab, wherein it is fard) Saying SubhanAllah when seeing beautiful natural scenery Reciting the Throne Verse or Surah al-Ikhlas when walking in nature Observing the crescent moon Saying the thunder du'a' when hearing thunder Waking up before Fajr (rather than staying up)
