Al-Husayn ibn Sa'id narrated from Al-Qasim ibn Urwah from Ubayd ibn Zurarah from his father: Abu Ja'far, peace be upon him, said: "If a prayer passes you by and you remember it during the time of another prayer, then if you know that by praying the one that you missed you will still have time to perform the current one within its time, begin with the one you missed, for Allah سبحانه وتعالى, the Mighty and Majestic, says: “And establish the prayer for My remembrance” (Surah Taha 20:14). But if you know that by praying the one you missed you will miss the current prayer, then begin with the one whose time you are in, and then perform the one you missed afterward."
