It is narrated from Sayyiduna Sahl bin Hunaif (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: A people will appear from the east, their heads will be shaved, and they will be involved in tribulations. And when the Messenger of Allah (peace and blessings be upon him) was asked about Madinah Munawwarah, he said: This is a sanctuary, a place of safety; this is a sanctuary, a place of safety.
