Musannaf Ibn Abi Shayba 21:157

Yahya ibn Sa'id narrated to us, from Sufyan, from Salamah ibn Kuhayl, from 'Abdullah ibn 'Abd al-Rahman ibn Abza, from his father, who said: When the Messenger of Allah (peace and blessings of Allah be upon him) would reach the morning, he would say: "We have reached the morning, and sovereignty has reached the morning for Allah, and pride, and greatness, and creation, and the command, and the night, and the day, and what appears in them, all belong to Allah alone, with no partner for Him. O Allah, make the beginning of this day righteousness, its middle success, and its end prosperity. I ask You for the good of the world, O Most Merciful of the merciful."
