Ibn 'Abbas (Allah be pleased with him) reported Allah's Messenger (ﷺ) as saying on the Day of Victory over Mecca:
There is no Hijra (emigration) but only Jihad and good intention; and when you are called to battle, then go forth. He also said on the Day of Victory over Mecca: Allah made this town sacred on the day He created the earth and the heavens; so it is -sacred by the sacred- ness conferred on it by Allah until the Day of Resurrection and fighting in it was not lawful to anyone before me, and it was made lawful for me only during an hour on one day, for it is sacred by the sacredness conferred on it by Allah until the Day of Resurrection. Its thorns are not to be cut, its game is not to be molested, and the things dropped are to be picked up only by one who makes a public announcement of it, and its fresh herbage is not to be cut. Abbas (Allah be pleased with him) said: Messenger of Allah, exception may be made in case of rush, for it is useful for their blacksmiths and for their houses. He (the Holy Prophet) conceding the suggestion of 'Abbas) said: Except rush.
