From him from Ya'qub ibn Yazid from Ibn Abi Umayr from Ibrahim ibn Abd Al-Hamid from some of our companions from Abu Abdillah عليه السلام, peace be upon him, and I think it was Ishaq ibn Ghalib, who said: He (ibn Ghalib) said: “When a man stands up during the night and thinks that dawn has arrived, so he performs the witr prayer, then he looks and realizes that it is still night” Imam عليه السلام said: "He should add a rak'ah to the witr, then resume the night prayer, and then perform the witr prayer after it."
