Hazrat Safiyyah bint Shaybah narrates that a woman told her that she heard the Prophet Muhammad (peace be upon him) say between Safa and Marwah: "(Believers) Running (Sa'i) has been made obligatory upon you, so you should run." Imam Abu Bakr (may Allah have mercy on him) says that the name of the woman not mentioned in this narration is Habibah bint Abi Tijarah.
