When the Messenger of Allah ﷺ started to pray, he would say Takbir, then say: "Wajahtu wajhi lilladhi fataras-samawatiwal-arda hanifan wa ma ana minal-mushrikin. Inna salati wa nusuki wa mahyaya wa mamati lillahi rabbil-alamin, la sharika lahu, wa bidhalika umirtu wa ana min al-muslimin. Allahumma! Antal-maliku la ilaha illa ant, ana abduka zalamtu nafsi wa'taraftu bidhanbi faghfirli dhunubi jami'an, la yaghfirudhunuba illa anta, wahdini lihasanil-ahklaqi, la yahdi li ahsaniha illa anta wasrif anni sayy'aha la yasrifu anni sayy'aha illa anta, labaika wa sa'daika, wal-khairu kulluhu fi yadaika wash-sharru laisa ilaika ana bika wa ilaika ana bika wa ilaika tabarkta wa ta'alaita astaghfiruka wa atubu ilaik. (Verily, I have turned my face toward Him who created the Heavens and the Earth hanifa (worhsipping none but Allah Alone), and I am not of the idolaters. Verily, my salah, my sacrifice, my living, and my dying are for Allah, the Lord of the all that exists. He has no partner. And of this I have been commanded, and I am one of the Muslims. O Allah, You are the Sovereign and there is none worthy of worship but You. I am Your slave, I have wronged myself and I acknowledge my sin. Forgive me all my sins for no one forgives sins but You. Guide me to the best of manners for none can guide to the best of them but You. Protect me from bad manners for none can protect against them but You. I am at Your service, all goodness is in Your hands, and evil is not attributed to You. I rely on You and turn to You, blessed and exalted are You, I seek Your forgiveness and repent to You." (Using translation from Nasāʾī 897)  

كَانَ رَسُولُ اللَّهِ ﷺ إِذَا افْتَتَحَ الصَّلَاةَ كَبَّرَ ثُمَّ قَالَ «وَجَّهْتُ وَجْهِيَ لِلَّذِي فَطَرَ السَّمَوَاتِ وَالْأَرْضَ حَنِيفًا وَمَا أَنَا مِنَ الْمُشْرِكِينَ إِنَّ صَلَاتِي وَنُسُكِي وَمَحْيَايَ وَمَمَاتِي لِلَّهِ رَبِّ الْعَالَمِينَ لَا شَرِيكَ لَهُ وَبِذَلِكَ أُمِرْتُ وَأَنَا أَوَّلُ الْمُسْلِمِينَ اللَّهُمَّ أَنْتَ الْمَلِكُ لَا إِلَهَ إِلَّا أَنْتَ أَنْتَ رَبِّي وَأَنَا عَبْدُكَ ظَلَمْتُ نَفْسِي وَاعْتَرَفْتُ بِذَنْبِي فَاغْفِرْ لِي ذُنُوبِي جَمِيعًا لَا يَغْفِرُ الذُّنُوبَ إِلَّا أَنْتَ وَاهْدِنِي لِأَحْسَنِ الْأَخْلَاقِ لَا يَهْدِي لِأَحْسَنِهَا إِلَّا أَنْتَ وَاصْرِفْ عَنِّي سَيِّئَهَا لَا يَصْرِفُ سَيِّئَهَا إِلَّا أَنْتَ لَبَّيْكَ وَسَعْدَيْكَ وَالْخَيْرُ كُلُّهُ فِي يَدَيْكَ وَالشَّرُّ لَيْسَ إِلَيْكَ أَنَا بِكَ وَإِلَيْكَ تَبَارَكْتَ وَتَعَالَيْتَ أَسْتَغْفِرُكَ وَأَتُوبُ إِلَيْكَ»  

[Machine] The translation of the provided text in English is as follows:

"When the Messenger of Allah ﷺ would get up at night, he would say: 'Glory be to You, O Allah, and praise be to You. Blessed is Your name and exalted is Your Majesty. There is no deity worthy of worship except You. I seek refuge in Allah, the All-Hearing, the All-Knowing, from Satan, the accursed, from his whispers, breaths, and blowing.' Then he would begin his prayer. Ja'far explained it as follows: 'His whispers refers to death, his breaths refers to poetry, and his blowing refers to arrogance.'"  

كَانَ رَسُولُ اللَّهِ ﷺ إِذَا قَامَ مِنَ اللَّيْلِ فَكَبَّرَ قَالَ سُبْحَانَكَ اللَّهُمَّ وَبِحَمْدِكَ وَتَبَارَكَ اسْمُكَ وَتَعَالَى جَدُّكَ وَلَا إِلَهَ غَيْرُكَ أَعُوذُ بِاللَّهِ السَّمِيعِ الْعَلِيمِ مِنَ الشَّيْطَانِ الرَّجِيمِ مِنْ هَمْزِهِ وَنَفْثِهِ وَنَفْخِهِ ثُمَّ يَسْتَفْتِحُ صَلَاتَهُ قَالَ جَعْفَرٌ وَفَسَّرَهُ مَطَرٌ هَمْزُهُ الْمُوتَةُ وَنَفْثُهُ الشِّعْرُ وَنَفْخُهُ الْكِبْرُ
