Drawing inference in the light of the preceding evidence, and on the basis that Allah, Mighty and Majestic, by His saying: "And the game of the land has been made unlawful for you as long as you are in the state of ihram." [Surah al-Ma'idah: 96] made unlawful for them in the state of ihram only that which was lawful for them before ihram and which they used to eat.
