Yahya related to me from Malik that Sumayy, the mawla of Abu Bakr (RA) ibn Abd ar-Rahman, heard Abu Bakribn Abd ar-Rahman say, "A woman came to the Messenger of Allah, may Allah bless him and grant him peace, and said, I had arranged to do hajj, but I was prevented, and the Messenger of Allah, may Allah bless him and grant him peace, said, Do umra in Ramadan, for doing umra in it is like doing hajj. "
