It is narrated from Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "I declare the area between the two boundaries of Madinah sacred, just as Ibrahim (peace be upon him) declared Makkah sacred. Therefore, no tree should be cut here, nor should any animal be hunted here. If anyone leaves this place out of dislike, Allah will settle someone better than him in his place. And for the people, Madinah is the best place if they only knew. And whoever intends evil against the people of Madinah, Allah will melt him just as copper melts in fire or salt dissolves in water."
