Al-Husayn ibn Sa’id, from Hammad ibn Isa, from Mu‘awiyah ibn Wahb, who said: I heard Abu Abdillah عليه السلام, peace be upon him, say: “My father (Imam al-Baqir عليه السلام), peace be upon him, used to call for water for purification (al-tahur) while on a journey, and he was in his litter (al-mahmil). A basin (al-tawr) containing water would be brought to him, and he would perform ablution, then he would pray the eight (rak‘ahs of night prayer) and the witr in his litter. Then, when He (Imam al-Baqir عليه السلام) dismounted, He عليه السلام would pray two rak‘ahs and the morning prayer (al-subh).”
