Abu Burdah reported: Abdullah ibn Umar said to me, “Have you heard anything narrated by your father from the Messenger of Allah, peace and blessings be upon him, about the special moment on Friday?” I said, “Yes. I heard him narrate that the Messenger of Allah said: It is the moment between the beginning of the sermon and the completion of the prayer.”
