At the start of the prayer (after takbeer)

اللّهُـمَّ باعِـدْ بَيـني وَبَيْنَ خَطـايايَ كَما باعَدْتَ بَيْنَ المَشْرِقِ وَالمَغْرِبْ ، اللّهُـمَّ نَقِّنـي مِنْ خَطايايَ كَمـا يُـنَقَّى الثَّـوْبُ الأَبْيَضُ مِنَ الدَّنَسْ ، اللّهُـمَّ اغْسِلْنـي مِنْ خَطايـايَ بِالثَّلـجِ وَالمـاءِ وَالْبَرَدْ.

O Allah, separate me from my sins as You have separated the East from the West. O Allah, cleanse me of my transgressions as the white garment is cleansed of stains. O Allah, wash away my sins with ice and water and frost.

Al-Bukhari 1/181, Muslim 1/419.

سُبْـحانَكَ اللّهُـمَّ وَبِحَمْـدِكَ وَتَبارَكَ اسْمُـكَ وَتَعـالى جَـدُّكَ وَلا إِلهَ غَيْرُك

Glory is to You O Allah, and praise. Blessed is Your Name and Exalted is Your Majesty. There is none worthy of worship but You

Abu Dawud, Ibn Majah, An-Nasa'i, At-Tirmidhi. See Al-Albani, Sahih At-Tirmidhi 1/77 and Sahih Ibn Majah 1/135.

وَجَّهـتُ وَجْهِـيَ لِلَّذي فَطَرَ السَّمـواتِ وَالأَرْضَ حَنـيفَاً وَمـا أَنا مِنَ المشْرِكين ، إِنَّ صَلاتـي ، وَنُسُكي ، وَمَحْـيايَ ، وَمَماتـي للهِ رَبِّ العالَمين ، لا شَريـكَ لَهُ وَبِذلكَ أُمِرْتُ وَأَنا مِنَ المسْلِـمين. اللّهُـمَّ أَنْتَ المَلِكُ لا إِلهَ إِلاّ أَنْت، أَنْتَ رَبِّـي وَأَنـا عَبْـدُك ، ظَلَمْـتُ نَفْسـي وَاعْـتَرَفْتُ بِذَنْبـي فَاغْفِرْ لي ذُنوبي جَميعاً إِنَّـه لا يَغْـفِرُ الذُّنـوبَ إلاّ أَنْت. وَاهْدِنـي لأَحْسَنِ الأَخْلاقِ لا يَهْـدي لأَحْسَـنِها إِلاّ أَنْـت ، وَاصْـرِف عَـنّْي سَيِّئَهـا، لا يَصْرِفُ عَـنّْي سَيِّئَهـا إِلاّ أَنْـت، لَبَّـيْكَ وَسَعْـدَيْك، وَالخَـيْرُ كُلُّـهُ بِيَـدَيْـك، وَالشَّرُّ لَيْـسَ إِلَـيْك ، أَنا بِكَ وَإِلَيْـك ، تَبـارَكْتَ وَتَعـالَيتَ أَسْتَغْـفِرُكَ وَأَتوبُ إِلَـيك

"I have turned my face sincerely towards He who has brought forth the heavens and the Earth and I am not of those who associate (others with Allah). Indeed my prayer, my sacrifice, my life and my death are for Allah, Lord of the worlds, no partner has He, with this I am commanded and I am of the Muslims. O Allah, You are the Sovereign, none has the right to be worshipped except You. You are my Lord and I am Your servant, I have wronged my own soul and have acknowledged my sin, so forgive me all my sins for no one forgives sins except You. Guide me to the best of characters for none can guide to it other than You, and deliver me from the worst of characters for none can deliver me from it other than You. Here I am, in answer to Your call, happy to serve you. All good is within Your hands and evil does not stem from You. I exist by your will and will return to you. Blessed and High are You, I seek Your forgiveness and repent unto You."

Muslim 1/534

اللّهُـمَّ رَبَّ جِـبْرائيل ، وَميكـائيل ، وَإِسْـرافيل، فاطِـرَ السَّمواتِ وَالأَرْض ، عالـِمَ الغَيْـبِ وَالشَّهـادَةِ أَنْـتَ تَحْـكمُ بَيْـنَ عِبـادِكَ فيـما كانوا فيهِ يَخْتَلِفـون. اهدِنـي لِمـا اخْتُـلِفَ فيـهِ مِنَ الْحَـقِّ بِإِذْنِك ، إِنَّـكَ تَهْـدي مَنْ تَشـاءُ إِلى صِراطٍ مُسْتَقـيم

O Allah, Lord of Jibraīl, Mīkaīl and Israfīl (great angels), Creator of the heavens and the Earth, Knower of the seen and the unseen. You are the arbitrator between Your servants in that which they have disputed. Guide me to the truth by Your leave, in that which they have differed, for verily You guide whom You will to a straight path."

Muslim 1/534

اللهُ أَكْبَـرُ كَبـيرا ، اللهُ أَكْبَـرُ كَبـيرا ، اللهُ أَكْبَـرُ كَبـيرا ، وَالْحَـمْدُ للهِ كَثـيرا ، وَالْحَـمْدُ للهِ كَثـيرا ، وَالْحَـمْدُ للهِ كَثـيرا ، وَسُبْـحانَ اللهِ بكْـرَةً وَأَصيـلا. ( ثَلاثاً ) أَعـوذُ بِاللهِ مِنَ الشَّـيْطانِ مِنْ نَفْخِـهِ وَنَفْـثِهِ وَهَمْـزِه

Allah is the Greatest, Most Great. Allah is the Greatest, Most Great. Allah is the Greatest, Most Great. Praise is to Allah, abundantly. Praise is to Allah, abundantly. Praise is to Allah, abundantly. Glory is to Allah, at the break of day and at its end. [Recite three times in Arabic.] I seek refuge in Allah from Satan. From his breath, and from his voice, and from his whisper.

Abu Dawud 1/203, Ibn Majah 1/265, ai Ahmad 4/85. Muslim recorded a similar Hadil 1/420.

اللّهُـمَّ لَكَ الْحَمْدُ أَنْتَ نـورُ السَّمـواتِ وَالأَرْضِ وَمَنْ فيـهِن ، وَلَكَ الْحَمْدُ أَنْتَ قَـيِّمُ السَّـمواتِ وَالأَرْضِ وَمَنْ فيـهِن ، [وَلَكَ الْحَمْدُ أَنْتَ رَبُّ السَّـمواتِ وَالأَرْضِ وَمَنْ فيـهِن] [وَلَكَ الْحَمْدُ لَكَ مُلْـكُ السَّـمواتِ وَالأَرْضِ وَمَنْ فيـهِن] [وَلَكَ الْحَمْدُ أَنْتَ مَلِـكُ السَّـمواتِ وَالأَرْضِ ] [وَلَكَ الْحَمْدُ] [أَنْتَ الْحَـقّ وَوَعْـدُكَ الْحَـق ، وَقَوْلُـكَ الْحَـق ، وَلِقـاؤُكَ الْحَـق ، وَالْجَـنَّةُحَـق ، وَالنّـارُ حَـق ، وَالنَّبِـيّونَ حَـق ، وَمـحَمَّدٌ حَـق ، وَالسّـاعَةُحَـق] [اللّهُـمَّ لَكَ أَسْلَمت ، وَعَلَـيْكَ تَوَكَّلْـت ، وَبِكَ آمَنْـت ، وَإِلَـيْكَ أَنَبْـت ، وَبِـكَ خاصَمْت ، وَإِلَـيْكَ حاكَمْـت . فاغْفِـرْ لي مـا قَدَّمْتُ ، وَما أَخَّـرْت ، وَما أَسْـرَرْت ، وَما أَعْلَـنْت ] [أَنْتَ المُقَـدِّمُ وَأَنْتَ المُـؤَخِّر ، لا إِاـهَ إِلاّ أَنْـت] [أَنْـتَ إِلـهي لا إِاـهَ إِلاّ أَنْـت

O Allah, praise is to You. You are the Light of the heavens and the earth and all that they contain. Praise is to You, You are the Sustainer of the heavens and the earth and all they contain. [Praise is to You, You are the Lord of the heavens and the earth and all they contain.] [Praise is to You, Yours is dominion of the heavens and the earth and all they contain.] [Praise is to You, You are the King of the heavens and the earth.] [And praise is to You.] [You are the Truth, Your Promise is true, Your Word is true, Your audience is true, Paradise is true, Hell is true, the Prophets are true, and Muhammad (peace and blessings be upon him) is true, and the Hour of Judgment is true.] [O Allah, to You I have submitted, and upon You I depend. I have believed in You and to You I turn in repentance . For Your sake I dispute and by Your standard I judge. Forgive me what I have sent before me and what I have left behind me, what I have concealed and what I have declared.] [You are the One Who sends forth and You are the One Who delays, there is none who has the right to be worshipped but You.] [You are my God, there is none who has the right to be worshipped but You.]
