Muhammad ibn Ahmad ibn Yahya, from Ibrahim, from Muhammad ibn ‘Umar al-Zayyat, from Jamil ibn Darraj, who said: I asked Abu al-Hasan al-Awwal عليه السلام (the First), peace be upon him, about making up the night prayer (‘salat al-layl’) after Fajr until the sun rises. Imam عليه السلام said: "Yes, and also after ‘Asr until night. This is from the concealed secrets of the family of Muhammad صلى الله عليه وعلى آله وسلم, may Allah سبحانه وتعالى bless him and his family."
