Musnad Ahmad 25:1416

Yahya ibn Adam narrated to us, Ibn Abi Za'idah narrated to us, from Dawud ibn Abi Hind, from 'Amr ibn Sa'id, from Sa'id ibn Jubayr, from Ibn 'Abbas: That the Prophet, peace and blessings of Allah be upon him, spoke to a man regarding something, and he said: "Indeed, all praise is due to Allah; we praise Him and we seek His help. Whoever Allah guides, there is no one to lead him astray, and whoever He leads astray, there is no one to guide him. And I bear witness that there is no god but Allah alone, with no partner, and I bear witness that Muhammad is His servant and His messenger."
