Ibn 'Abbas reported that the Messenger of Allah (ﷺ) used to recite in first of the two (supererogatory) rak'ahs of the dawn:" Say: We believed in Allah and what was revealed to us..." verses 285-286 from Surah Baqarah, and in the second of the two: "I believe in Allah and I bear testimony that we are Muslims" (iii. 51).
