It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "I saw in a dream a black, disheveled-haired woman leaving Madinah and stopping at Mahya‘ah, that is, Juhfah. I interpreted it as meaning that the epidemics and afflictions of Madinah have been transferred to Juhfah."
