Abdullah bin Abbas reported,

The Messenger of Allah ﷺ said on the day of the Conquest of Mecca, "There is no migration after the conquest, but only jihad and intention. So if you are called to march out, then march out."He also said on the day of the Conquest of Mecca, "This land was made sacred by Allah on the day He created the heavens and the earth. It is sacred by the sanctity of Allah until the Day of Resurrection. Fighting in it was not permitted to anyone before me, and it was permitted to me only for an hour of one day. It is sacred by the sanctity of Allah until the Day of Resurrection. Its thorny shrubs are not to be cut, its game is not to be startled, its lost property is not to be picked up except by one who will announce it, and its fresh grass is not to be cut."Abbas said, "Messenger of Allah, except for idhkhir, for it is used by their blacksmiths and in their houses."He replied, "Except for idhkhir."

عن ابن عباس قال

قال رسول الله ﷺ يوم الفتح فتح مكة: لا هجرة ولكن جهاد ونية، وإذا استنفرتم فانفروا وقال يوم الفتح فتح مكة: إن هذا البلد حرمه الله يوم خلق السموات والأرض فهو حرام بحرمة الله إلى يوم القيامة، وإنه لم يحل القتال فيه لأحد قبلي، ولم يحل لي إلا ساعة من نهار، فهو حرام بحرمة الله إلى يوم القيامة، لا يعضد شوكه، ولا ينفر صيده، ولا يلتقط إلا من عرفها، ولا يختلى خلاها فقال العباس: يا رسول الله، إلا الإذخر؛ فإنه لقينهم ولبيوتهم فقال: إلا الإذخر.
