﴿ أُحِلَّ لَكُمْ صَيْدُ ٱلْبَحْرِ وَطَعَامُهُۥ مَتَٰعًۭا لَّكُمْ وَلِلسَّيَّارَةِ ۖ وَحُرِّمَ عَلَيْكُمْ صَيْدُ ٱلْبَرِّ مَا دُمْتُمْ حُرُمًۭا ۗ وَٱتَّقُوا۟ ٱللَّهَ ٱلَّذِىٓ إِلَيْهِ تُحْشَرُونَ ﴾

“Lawful to you is all water-game, and what the sea brings forth, 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. And be conscious of God, unto whom you shall be gathered.”
