Sunan Abi Dawud Book 5, Hadith 10
The Messenger of Allah (ﷺ) used to recite in both rak'ahs of the dawn prayer: "Say: We believe in Allah and in the revelation given to us" (3:84) . This is in the first rak'ah and in the second rak'ah (he recited): "We believe in Allah and bear witness that we submit ourself (to Him)." (3:52).
The Prophet (ﷺ) said: Do not omit them (the two rak'ahs before the dawn prayer) even if you are driven away by the horses.
That he heard the Prophet (ﷺ) recite in both rak'ahs of the dawn: "Say: We believe in Allah, and in the revelation given to us" (3:84). This is in the first rak'ah. In the second rak'ah he recited this verse: "Our Lord, we have believed in what You have sent down, and we follow the Messenger, so write us down among those who bear witness." or he recited: "Surely, we have sent you with the truth as a bringer of glad tidings, and a warner. And you will not be asked about the inhabitants of the Blazing Fire" (2:119). Al-Darawardi doubted (which of the verse he recited).
