Al-Husayn ibn Sa'id, from al-Nadr ibn Suwayd, from Zur’ah ibn Muhammad, from Sama’ah, who said: I asked Abu Abdillah عليه السلام, peace be upon him, about the time of the night prayer (salat al-layl) during travel. Imam عليه السلام said: “From the time you pray the 'atamah (nightfall prayer) until the break of dawn (fajr).”
