It is narrated from Umm al-Mu'minin Sayyidah Aisha (may Allah be pleased with her) that one night the Messenger of Allah (peace and blessings be upon him) stood up and put on his clothes, then he went out. So I told my slave-girl Barirah to follow behind the Messenger of Allah (peace and blessings be upon him), so she went until the Messenger of Allah (peace and blessings be upon him) reached Baqi' and stood near it for as long as Allah willed him to stand. Then the Messenger of Allah (peace and blessings be upon him) returned, and Barirah reached me before the Messenger of Allah (peace and blessings be upon him) did. I did not mention anything to the Messenger of Allah (peace and blessings be upon him) until morning came. Then I mentioned it to him, and he said: "I was commanded to go to the people of Baqi' so that I may supplicate for them."
