Musnad Ahmad Hadith 2344

"This is a sacred land; Allah made it sacred on the day He created the heavens and the earth. It is sacred; Allah has made it sacred until the Day of Resurrection. It was not made permissible to anyone to fight in it apart from me, and it will not be permissible for anyone after me to fight in it until the Day of Resurrection. It was only made permissible for me for part of a day. It is a sanctuary made sacred by Allah, may He be glorified and exalted, until the Hour begins. Its thorns are not to be cut, its green grass is not to be uprooted, its game is not to be disturbed and its lost property is not to be picked up except by the one who will announce it.” al 'Abbas - who was one of the local people and knew what they could not do without - said: Except idhkhir, O Messenger of Allah, for they need it for their graves and houses. And the Messenger of Allah (ﷺ) said: “Except idhkhir."
