And from him, from al-Hasan ibn Ali, from Ibn Bukayr, from Zurarah, who said: I asked Abu Ja’far عليه السلام about making up the night prayer (‘salat al-layl’). Imam عليه السلام said: "Make it up at the same time in which you used to perform it." I asked: “Will there be two ‘witr’ prayers in one night?” Imam عليه السلام said: "It is not considered two ‘witrs’ in one night, one of them is for what you missed."
