What Is Makruh? Are Sea Prawns Makruh?
All catch of the sea is pronounced halal per Quran. Please see 5:96. 5:96 Lawful to you is all water-game, and what the sea brings forth,115 as a provision for you [who are settled] as well as for travellers, although you are forbidden to hunt on land while you are in the state of pilgrimage.116 And be conscious of God, unto whom you shall be gathered. Muhammad Asad (The Message Of Quran).
