Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said that the Messenger of Allah (peace and blessings be upon him) was shown (a vision) at his resting place in the last part of the night at Dhu al-Hulayfah, in the bed of the valley, and it was said to him: "You are in a blessed valley (Batha')." Musa (may Allah have mercy on him) said: Salim (may Allah have mercy on him) made his riding camel kneel at the very spot where Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) used to make his camel kneel, seeking out the resting place of the Messenger of Allah (peace and blessings be upon him). It is below the mosque that is in the bed of the valley, midway between it and the road.
