Musnad Ahmad 5:242

Hujayn narrated to us, Abd al-Aziz narrated to us, from his paternal uncle al-Majishun ibn Abi Salamah, from Abd al-Rahman al-A'raj, from Ubayd Allah ibn Abi Rafi, from Ali ibn Abi Talib, from the Messenger of Allah (peace and blessings of Allah be upon him), that when he began the prayer, he would say the takbir, then say: "I have turned my face toward Him who created the heavens and the earth, inclining toward the truth, and I am not of the polytheists. Indeed, my prayer, my sacrifice, my living, and my dying are for Allah, Lord of the worlds. No partner has He. And of this I have been commanded, and I am of the Muslims. O Allah, You are the Sovereign; there is no god but You. You are my Lord and I am Your servant. I have wronged my soul and I have confessed my sin, so forgive me all my sins, for none forgives sins except You. And guide me to the best of characters, for none guides to the best of them except You. And turn away from me their evil, for none turns away their evil except You." He mentioned the like of it, except that he said: "And turn away from me their evil."
