Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: In the two rak'ahs before Fajr, the Messenger of Allah (peace and blessings be upon him) would recite in the first rak'ah Surah al-Fatihah and the two verses at the end of Surah al-Baqarah which begin: "The Messenger has believed in what was revealed to him from his Lord" [Surah al-Baqarah: 285]; and in the second rak'ah Surah al-Fatihah and this verse of Surah Al Imran: "Say: O People of the Book, come to a word that is equitable between us and you" [Surah Al Imran: 64] to the end of the verse.
