It is narrated from Sayyiduna Ali (may Allah be pleased with him) that when the Prophet (peace and blessings be upon him) would say the opening takbeer, after reciting the thana, he would say: «وَجَّهْتُ وَجْهِي لِلَّذِي فَطَرَ السَّمَوَاتِ وَالْأَرْضَ حَنِيفًا وَمَا أَنَا مِنْ الْمُشْرِكِينَ إِنَّ صَلَاتِي وَنُسُكِي وَمَحْيَايَ وَمَمَاتِي لِلّٰهِ رَبِّ الْعَالَمِينَ لَا شَرِيكَ لَهُ وَبِذَلِكَ أُمِرْتُ وَأَنَا أَوَّلُ الْمُسْلِمِينَ اَللّٰهُمَّ أَنْتَ الْمَلِكُ لَا إِلٰهَ إِلَّا أَنْتَ أَنْتَ رَبِّي وَأَنَا عَبْدُكَ ظَلَمْتُ نَفْسِي وَاعْتَرَفْتُ بِذَنْبِي فَاغْفِرْ لِي ذُنُوبِي جَمِيعًا لَا يَغْفِرُ الذُّنُوبَ إِلَّا أَنْتَ اَللَّهُمَّ اهْدِنِي لِأَحْسَنِ الْأَخْلَاقِ لَا يَهْدِي لِأَحْسَنِهَا إِلَّا أَنْتَ اصْرِفْ عَنِّي سَيِّئَهَا لَا يَصْرِفُ عَنِّي سَيِّئَهَا إِلَّا أَنْتَ لَبَّيْكَ وَسَعْدَيْكَ وَالْخَيْرُ كُلُّهُ فِي يَدَيْكَ وَالشَّرُّ لَيْسَ إِلَيْكَ أَنَا بِكَ وَإِلَيْكَ تَبَارَكْتَ وَتَعَالَيْتَ أَسْتَغْفِرُكَ وَأَتُوبُ إِلَيْكَ» "I have turned my face, being upright and in submission, towards Him Who created the heavens and the earth, and I am not among the polytheists. My prayer, my sacrifice, my life, and my death are for Allah, the Lord of all the worlds. He has no partner. This is what I have been commanded, and I am among the Muslims. O Allah! You are the true King, there is no deity except You, You are my Lord and I am Your servant. I have wronged myself, and I confess my sins, so forgive all my sins, for none forgives sins except You. Guide me to the best of character, for none guides to the best of character except You, and turn me away from bad character, for none can turn me away from it except You. I am present before You and at Your service. All kinds of good are in Your hands, and evil cannot approach You. I belong to You and will return to You. You are Most Blessed and Most Exalted. I seek Your forgiveness for my sins and I repent to You." When he would go into ruku, he would say: «اَللّٰهُمَّ لَكَ رَكَعْتُ وَبِكَ آمَنْتُ وَلَكَ أَسْلَمْتُ خَشَعَ لَكَ سَمْعِي وَبَصَرِي وَمُخِّي وَعِظَامِي وَعَصَبِي» "O Allah! I have bowed to You, I have believed in You, I have submitted to You. My hearing, my sight, my mind, my bones, and my tendons are all humbled before You." When he would rise from ruku, after saying 'Sami Allahu liman hamidah' and 'Rabbana wa lakal hamd', he would say: «لَكَ الْحَمْدُ مِلْءَ السَّمَوَاتِ وَالْأَرْضِ وَمَا بَيْنَهُمَا وَمِلْءَ مَا شِئْتَ مِنْ شَيْءٍ بَعْدُ» "All praise is for You, filling the heavens, the earth, and whatever is between them, and whatever else You will to fill." When the Prophet (peace and blessings be upon him) would go into prostration, he would say: «اَللّٰهُمَّ لَكَ سَجَدْتُ وَبِكَ آمَنْتُ وَلَكَ أَسْلَمْتُ سَجَدَ وَجْهِي لِلَّذِي خَلَقَهُ وَصَوَّرَهُ فَأَحْسَنَ صُوَرَهُ فَشَقَّ سَمْعَهُ وَبَصَرَهُ فَتَبَارَكَ اللّٰهُ أَحْسَنُ الْخَالِقِينَ» "O Allah! I have prostrated for You, I have believed in You, I have submitted to You. My face has prostrated before the One Who created it and fashioned it well, and gave it hearing and sight. Blessed is Allah, the Best of creators." And when he would finish the prayer with salam, he would say: «اَللّٰهُمَّ اغْفِرْ لِيْ مَا قَدَّمْتُ وَمَا أَخَّرْتُ وَمَا أَسْرَرْتُ وَمَا أَعْلَنْتُ وَمَا أَسْرَفْتُ وَمَا أَنْتَ أَعْلَمُ بِهِ مِنِّي أَنْتَ الْمُقَدِّمُ وَأَنْتَ الْمُؤَخِّرُ لَا إِلٰهَ إِلَّا أَنْتَ» "O Allah! Forgive all my past and future, hidden and apparent sins, and whatever excess I have committed, and whatever You know better than I do. You are the First and the Last, and there is no deity except You."
