It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: Every prophet has a sanctuary, and my sanctuary is Madinah. O Allah! I declare it a sanctuary by Your permission. No innovator or sinner should be able to seek refuge here. Its trees should not be cut, nor its grass mown, and except for the announcer, no one else is permitted to pick up anything fallen here.
