Amatul Rahmân Omer:
They ask you what is made lawful for them. Say, `All good and pure things are made lawful for you. Also (made lawful) is the game held down by those birds and beasts of prey which you have trained, provided you set them at it to catch (it living) for you, (without their own eating from it after killing it), since you train them according to the knowledge Allâh has given you. So eat of that which they hold down for you and pronounce thereon the name of Allâh (while slaughtering it or while sending the hunting creatures after it). And take Allâh as a shield. Surely, Allâh is Swift in reckoning.
Surah Al Maidah (The Table Spread with Food) Ayat 4
