In Islamic terminology, something which is makruh (Arabic: , transliterated: makrooh or makr?h) is a disliked or offensive act (literally "detestable" or "abominable"). This is one of the five categories (al-ahkam al-khamsa) in Islamic law - wajib/fard (obligatory), Mustahabb/mandub (recommended), mubah (neutral), makruh (disapproved), haram (forbidden).
Though a makruh act is not haram (forbidden) or subject to punishment, a person who abstains from this act will be rewarded.Muslims are encouraged to avoid such actions when or as possible. It is one of the degrees of approval (ahkam) in Islamic law.
Examples of something considered Makruh are the use of a great amount of water when performing ritual purifications known as the wudu (partial ablution, or abdest) and ghusl (full ablution) or the consumption of garlic before attending the mosque or socializing with others.
An example of a food which is considered Makruh for Muslims of the Hanafi Madh'hab is prawns (but only for Hanafi Madh'hab). There are, however, shared attitudes within the Hanafi school of whether shrimp are considered water game and are thereby halal. Hanafis believe that you should refrain from it and eat something else if possible.
Other examples of Makruh acts in Islam include swearing, talking while taking ablutions for prayer, biting nails, and slaughtering an animal for food where other animals of its kind can see it.
