Abu Hurayrah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) recited: {Say, “O disbelievers”} and {Say: “He is Allah, the One”} in the two Rak‘ahs of Fajr.

The Prophet (may Allah's peace and blessings be upon him) used to prefer reciting {Say, “O disbelievers} [Surat al-Kāfirūn] in the first Rak‘ah of the Fajr confirmed voluntary prayer, after reciting Surat al-Fātihah, and {Say: “He is Allah, the One} [Surat al-Ikhlās] in the second Rak‘ah.
