Ali from his father from Ibn Abi Umayr from Ibn Udhaynah from Zurarah who said: I said to Abu Ja'far, peace be upon him: “The two rak'ahs before the morning prayer (Fajr), when is their time?” Imam عليه السلام said: "Before the rising of the dawn; and when the dawn rises, then the time for the morning prayer has entered."
