Scholars differ. Most hold that all sea animals are lawful, because the Quran says that the game of the sea and its food are permitted (5:96). The Hanafi school allows only fish and not other sea animals such as shrimp, though many Hanafi scholars today permit shrimp. Follow the view of the school or scholar you rely on.
Nyinyi mmehalalishiwa kuvua vinyama vya baharini na kuvila, kwa faida yenu na kwa wasafiri. Na mmeharimishiwa mawindo ya wanyama wa bara maadamu mmeharimia Hija. Na mcheni Mwenyezi Mungu ambaye mtakusanywa kwake.
Yeye ndiye aliye ifanya bahari ikutumikieni, ili kutokana na humo mpate kula nyama laini, na mtoe humo mapambo mnayo yavaa. Na unaona marikebu zikikata maji humo, ili mtafute fadhila yake, na mpate kushukuru.
