It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "Indeed, Allah Almighty has made His sanctuary (Haram) sacred, so it is sacred until the Day of Resurrection: its trees are not to be cut, its grass is not to be uprooted, its lost property is not to be picked up except by one who intends to announce it, and its game is not to be treated as lawful."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Nafi' (may Allah have mercy on him) except Isa al-Hannat (may Allah have mercy on him)."
