The Messenger of Allah ﷺ said, "This is Mecca. Allah made it sacred the day He created the heavens and the earth. It was never lawful for anyone before me, nor will it be lawful for anyone after me. It was made lawful for me only for an hour of one day, and this is that hour. It is sacred by the sanctity of Allah until the Day of Resurrection. Its grass is not to be uprooted, its trees are not to be cut, its game is not to be startled, and its lost property is not to be picked up except by one who will announce it."Then Abbas, who was a man of experience, stood up and said, "Except for idhkhir grass, for it is used in our houses and our graves."So he said, "Except for idhkhir."
أخبرنا سعيد بن عبد الرحمن قال حدثنا سفيان عن عمرو عن عكرمة
أن رسول الله ﷺ قال هذه مكة حرمها الله عز وجل يوم خلق السموات والأرض لم تحل لأحد قبلي ولا لأحد بعدي وإنما أحلت لي ساعة من نهار وهي ساعتي هذه حرام بحرام الله إلى يوم القيامة لا يختلى خلاها ولا يعضد شجرها ولا ينفر صيدها ولا تحل لقطتها إلا لمنشد فقام العباس وكان رجلا مجربا فقال إلا الإذخر فإنه لبيوتنا وقبورنا فقال إلا الإذخر
