Chapter on the Prayer Times (Mawaqit)

Ali narrated from his father from Hammad ibn Isa from Hariz from Zurarah: Abu Ja'far, peace be upon him, said: "If two witr prayers, or three, or more than that have accumulated upon you, then make them up in the same order in which you missed them. Separate between each two witr prayers with a (supererogatory) prayer. Do not perform anything before the first one. The first, then the first, you begin by making up the prayer of your own night, then the witr." He said, and Abu Ja'far عليه السلام, peace be upon him, also said: "There are not two Witrs in one night except that one of them is a makeup." And Imam عليه السلام said: "If you performed Witr at the beginning of the night and then you rise at the end of the night, then your first Witr is a makeup. And whatever you have prayed from the prayers during your entire night, let them be considered as makeup until the end of your prayers, for they are for your night. And let the last of your prayers be the Witr of your night."
