The Messenger of Allah (ﷺ) said on the day of the conquest of Makkah: "This land is sacred, for Allah has made it sacred. Fighting therein was not permitted to anyone before me, and it was permitted to me for a short while. It is sacred by the decree of Allah until the Day of Resurrection. Its game is not to be disturbed, its thorns are not to be cut, its lost property is not to be picked up except by one who will announce it, and its grasses are not to be cut." Al-'Abbas said. O Messenger of Allah, except idhkhir (a kind of grass), for it is used for their houses and by their blacksmiths. He said: “Except idhkhir. And there is no more migration (hijrah), but there is jihad and intention, and if you are asked to mobilise, then mobilise."
