Imam عليه السلام said: "The people missed the Dhuhr, Asr, Maghrib, and Isha prayers with Ali عليه السلام on the day of Siffin. He instructed them to make the takbir (saying 'Allahu Akbar'), tahleel (saying 'La ilaha illa Allah سبحانه وتعالى'), and tasbih (glorifying Allah سبحانه وتعالى) while standing and while mounted."
