باب فِي تَخْفِيفِهِمَا
Sunan Abi Dawud 1260
Narrated Abu Hurairah:
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).
