Sayyiduna Ka'b bin Malik (may Allah be pleased with him) said: "The Messenger of Allah (peace and blessings be upon him) declared the trees of Madinah sacred (forbidding their cutting) within an area of one barid by one barid, and he sent me, so I placed markers on the boundaries of the sanctuary: on the height of Dhat al-Jaysh, on Sharith, on Makhid and on Nabt."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Ka'b (may Allah be pleased with him) only with this chain, and Ibrahim bin al-Mundhir is alone in narrating it."
