That when he stood for prayer, he would say: "I have turned my face toward He who created the heavens and the earth, inclining to Him, and I am not among those who associate partners with Allah. Indeed, my prayer, my sacrifice, my life, and my death are for Allah, Lord of the worlds. He has no partner, and thus I have been commanded, and I am among the Muslims."
when the Prophet stood up for prayer (a version saying, when he began the prayer) he said the takbir , then said, “I have turned my face as a hanif * towards Him who created the heavens and the earth, and I am not a polytheist. My prayer and my devotion, my life and my death belong to God the Lord of the universe, who has no partner. That is what I have been commanded, and I am a Muslim. O God, Thou art the King. There is no god but Thee. Thou art my Lord and I am Thy servant. I have wronged myself, but I acknowledge my sin, so forgive me all my sins, Thou who alone canst forgive sins; and guide me to the best qualities, Thou who alone canst guide to the best of them; and turn me from evil ones, Thou who alone canst turn from evil qualities. I come to serve and please Thee. All good is in Thy hands and evil does not pertain to Thee. I seek refuge in Thee and turn to Thee, who art blessed and exalted. I ask Thy forgiveness and turn to Thee in repentance.” When he bowed he said, “O God, to Thee I bow, in Thee I trust, and to Thee I submit myself. My hearing, my sight, my brain, my bone and my sinews humble themselves before Thee.” When he raised his head he said, “O God, to Thee belongs praise in the whole of the heavens and the earth and what is between them, and in whatever Thou createst afterwards.” When he prostrated himself he said, “O God, to Thee I prostrate myself, in Thee I trust, and to Thee I submit myself. My face has prostrated itself before Him who created it, fashioned it, and brought forth its hearing and seeing. Blessed is God, the best of creators.” Then at the end of what he said between uttering the tahiyat and the taslim was, “O God, forgive me my former and latter sins, my open and my secret sins, my sins of negligence, and what Thou knowest better than I. Thou art He who puts forward and puts back. There is no god but Thee.” أنه كان إذا قام إلى الصلاة قال: وجهت وجهي للذي فطر السماوات والأرض حنيفا وما أنا من المشركين إن صلاتي ونسكي ومحياي ومماتي لله رب العالمين لا شريك له وبذلك أمرت وأنا من المسلمين، اللهم أنت الملك لا إله إلا أنت أنت ربي وأنا عبدك ظلمت نفسي واعترفت بذنبي فاغفر لي ذنوبي جميعا إنه لا يغفر الذنوب إلا أنت واهدني لأحسن الأخلاق لا يهدي لأحسنها إلا أنت واصرف عني سيئها لا يصرف عني سيئها إلا أنت، لبيك وسعديك والخير كله في يديك والشر ليس إليك أنا بك وإليك تباركت وتعاليت أستغفرك وأتوب إليك ، وإذا ركع قال: اللهم لك ركعت وبك ءامنت ولك أسلمت خشع لك سمعي وبصري ومخي وعظمي وعصبي ، وإذا رفع قال: اللهم ربنا لك الحمد ملء السماوات وملء الأرض وملء ما بينهما وملء ما شئت من شيء بعد ، وإذا سجد قال: اللهم لك سجدت وبك ءامنت ولك أسلمت سجد وجهي للذي خلقه وصوّره وشق سمعه وبصره تبارك الله أحسن الخالقين ، ثم يقول من ءاخر ما يقول بين التشهّد والتسليم: اللهم اغفر لي ما قدمت وما أخرت وما أسررت وما أعلنت وما أسرفت وما أنت أعلم به مني أنت المقدّم وأنت المؤخر لا إله إلا أنت Mishkat al-Masabih 813
