Abdullah bin Mas'ud (RA) narrated: "The Messenger of Allah (ﷺ) taught us the Tashah-hud for Salat and the Tashah-hud for Al-Hajjah." He said: "The Tashah-hud for Salat is:

إِنَّ الْحَمْدَ لِلَّهِ نَحْمَدُهُ وَنَسْتَعِينُهُ وَنَسْتَغْفِرُهُ وَنَعُوذُ بِاللَّهِ مِنْ شُرُورِ أَنْفُسِنَا وَمِنْ سَيِّئَاتِ أَعْمَالِنَا، مَنْ يَهْدِهِ اللَّهُ فَلَا مُضِلَّ لَهُ وَمَنْ يُضْلِلْ فَلَا هَادِيَ لَهُ أَشْهَدُ أَنْ لَّا إِلَهَ إِلَّا اللَّهُ وَأَشْهَدُ أَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ يَا أَيُّهَا الَّذِينَ آمَنُوا اتَّقُوا اللَّهَ حَقَّ تُقَاتِهِ وَلَا تَمُوتُنَّ إِلَّا وَأَنْتُمْ مُّسْلِمُونَ يَا أَيُّهَا النَّاسُ اتَّقُوا رَبَّكُمُ الَّذِي خَلَقَكُمْ مِّن نَّفْسٍ وَاحِدَةٍ وَخَلَقَ مِنْهَا زَوْجَهَا وَبَثَّ مِنْهُمَا رِجَالًا كَثِيرًا وَنِسَاءً ۚ وَاتَّقُوا اللَّهَ الَّذِي تَسَاءَلُونَ بِهِ وَالْأَرْحَامَ ۚ إِنَّ اللَّهَ كَانَ عَلَيْكُمْ رَقِيبًا يَا أَيُّهَا الَّذِينَ آمَنُوا اتَّقُوا اللَّهَ وَقُولُوا قَوْلًۭا سَدِيدًا يُصْلِحْ لَكُمْ أَعْمَالَكُمْ وَيَغْفِرْ لَكُمْ ذُنُوبَكُمْ وَمَنْ يُطِعِ اللَّهَ وَرَسُولَهُ فَقَدْ فَازَ فَوْزًا عَظِيمًا

Indeed all Praise is for Allah, we praise Him, we seek His help and we ask His forgiveness. We seek refuge with Allah from the evil of our own souls and from the evil of our actions. Whoever Allah guides will never be led astray,and whomever Allah leads astray, no one can guide. I bear witness that there is no deity worthy of worship except Allah, and I bear witness that Muhammad is His slave and Messenger. (then reads the following verses) O you who believe! Fear Allah as He should be feared, and die not except as Muslims; [1] O Mankind! Fear your Lord, Who created you from a single person, and from him created his wife, and from them he created many men and women, and fear Allah through Whom you demand your mutual (rights). Surely, Allah is Ever Watchful over you; [2] O you who believe! Fear Allah, and speak (always) the truth He will direct you to do righteous good deeds and will forgive you your sins. And whosoever obeys Allah and His Messenger has indeed achieved a great success. [3] Then he would talk about his needs. [4]
