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).  

أَنَّهُ سَمِعَ النَّبِيَّ ﷺ يَقْرَأُ فِي رَكْعَتَىِ الْفَجْرِ { قُلْ آمَنَّا بِاللَّهِ وَمَا أُنْزِلَ عَلَيْنَا } فِي الرَّكْعَةِ الأُولَى وَفِي الرَّكْعَةِ الأُخْرَى بِهَذِهِ الآيَةِ { رَبَّنَا آمَنَّا بِمَا أَنْزَلْتَ وَاتَّبَعْنَا الرَّسُولَ فَاكْتُبْنَا مَعَ الشَّاهِدِينَ } أَوْ { إِنَّا أَرْسَلْنَاكَ بِالْحَقِّ بَشِيرًا وَنَذِيرًا وَلاَ تُسْأَلُ عَنْ أَصْحَابِ الْجَحِيمِ } شَكَّ الدَّرَاوَرْدِيُّ
