“When we performed prayer with the Prophet ﷺ we said: ‘Peace be upon Allah from His slaves, peace be upon Jibra’il and Mika’il and so-and-so and so-and- so.’ The Messenger of Allah ﷺ heard us and said: ‘Do not say peace (Salam) be upon Allah, for He is As-Salam. When you sit (during prayer) say: At-Tahiyyatu lillahi was-salawatu wat-tayyibatu; as- salamu ‘alayka ayyuhan-Nabiyyu wa rahmatullahi wa barakatuhu; as- salamu ‘alayna wa ‘ala ‘ibadillahis-salihin (All compliments, prayers and good words are due to Allah; peace be upon you, O Prophet, and the mercy of Allah and His blessings; peace be upon us and upon the righteous slaves of Allah).” For as you say that it will reach every righteous slave in the heavens and on earth. (Then say:) “Ashhadu an la ilaha illallah wa ashhadu anna Muhammadan ‘abduhu wa Rasuluhu (I bear witness that none has the right to be worshipped but Allah, and I bear witness that Muhammad is His slave and Messenger).” (Another chain) with similar wording. (Another chain) that ʿAbdullah bin Masʿud said: "The Prophet ﷺ used to teach us the Tashahhud." And he mentioned similarly.  

كُنَّا إِذَا صَلَّيْنَا مَعَ النَّبِيِّ ﷺ قُلْنَا السَّلاَمُ عَلَى اللَّهِ قَبْلَ عِبَادِهِ السَّلاَمُ عَلَى جِبْرَائِيلَ وَمِيكَائِيلَ وَعَلَى فُلاَنٍ وَفُلاَنٍ يَعْنُونَ الْمَلاَئِكَةَ فَسَمِعَنَا رَسُولُ اللَّهِ ﷺ فَقَالَ لاَ تَقُولُوا السَّلاَمُ عَلَى اللَّهِ فَإِنَّ اللَّهَ هُوَ السَّلاَمُ فَإِذَا جَلَسْتُمْ فَقُولُوا التَّحِيَّاتُ لِلَّهِ وَالصَّلَوَاتُ وَالطَّيِّبَاتُ السَّلاَمُ عَلَيْكَ أَيُّهَا النَّبِيُّ وَرَحْمَةُ اللَّهِ وَبَرَكَاتُهُ السَّلاَمُ عَلَيْنَا وَعَلَى عِبَادِ اللَّهِ الصَّالِحِينَ فَإِنَّهُ إِذَا قَالَ ذَلِكَ أَصَابَتْ كُلَّ عَبْدٍ صَالِحٍ فِي السَّمَاءِ وَالأَرْضِ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَأَشْهَدُ أَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ حَدَّثَنَا مُحَمَّدُ بْنُ يَحْيَى حَدَّثَنَا عَبْدُ الرَّزَّاقِ أَنْبَأَنَا الثَّوْرِيُّ عَنْ مَنْصُورٍ وَالأَعْمَشِ وَحُصَيْنٍ وَأَبِي هَاشِمٍ وَحَمَّادٍ عَنْ أَبِي وَائِلٍ وَعَنْ أَبِي إِسْحَاقَ عَنِ الأَسْوَدِ وَأَبِي الأَحْوَصِ عَنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ عَنِ النَّبِيِّ ﷺ نَحْوَهُ حَدَّثَنَا مُحَمَّدُ بْنُ مَعْمَرٍ حَدَّثَنَا قَبِيصَةُ أَنْبَأَنَا سُفْيَانُ عَنِ الأَعْمَشِ وَمَنْصُورٍ وَحُصَيْنٍ عَنْ أَبِي وَائِلٍ عَنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ ح قَالَ وَحَدَّثَنَا سُفْيَانُ عَنْ أَبِي إِسْحَاقَ عَنْ أَبِي عُبَيْدَةَ وَالأَسْوَدِ وَأَبِي الأَحْوَصِ عَنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ أَنَّ النَّبِيَّ ﷺ كَانَ يُعَلِّمُهُمُ التَّشَهُّدَ فَذَكَرَ نَحْوَهُ  

“The Messenger of Allah ﷺ used to teach us the Tashah-hud as he used to teach us a Surah of the Qur’an. He used to say: ‘At-Tahiyyatul-Mubarakatus salawatut-tayyibatu lillah; As-salamu ‘alayka ayyuhan-Nabiyyu wa rahmatullahi wa barakatuhu; as-salamu ‘alayna wa ‘ala ‘ibadillahis-salihin. Ashhadu an la ilaha illallah wa ashhadu anna Muhammadan ‘abduhu wa Rasuluhu (All blessed compliments and good prayers are due to Allah; peace be upon you, O Prophet, and the mercy of Allah and His blessings; peace be upon us and upon the righteous slaves of Allah. I bear witness that none has the right to be worshipped but Allah and I bear witness that Muhammad is His slave and Messenger).’”  

كَانَ رَسُولُ اللَّهِ ﷺ يُعَلِّمُنَا التَّشَهُّدَ كَمَا يُعَلِّمُنَا السُّورَةَ مِنَ الْقُرْآنِ فَكَانَ يَقُولُ التَّحِيَّاتُ الْمُبَارَكَاتُ الصَّلَوَاتُ الطَّيِّبَاتُ لِلَّهِ السَّلاَمُ عَلَيْكَ أَيُّهَا النَّبِيُّ وَرَحْمَةُ اللَّهِ وَبَرَكَاتُهُ السَّلاَمُ عَلَيْنَا وَعَلَى عِبَادِ اللَّهِ الصَّالِحِينَ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَأَشْهَدُ أَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ  

“The Messenger of Allah ﷺ addressed us and explained the Sunnah for us, and he taught us our prayer. He said: ‘When you perform prayer, and you are sitting, let the first thing you say be: At-Tahiyyatut-tayyibatus-salawatu lillah; as-salamu ‘alayka ayyuhan-Nabiyyu wa rahmatullahi wa barakatuhu; as-salamu ‘alayna wa ‘ala ‘ibadillahis-salihin. Ashhadu an la ilaha illallah wa ashhadu anna Muhammadan ‘abduhu wa Rasuluhu (All compliments, good words and prayers are due to Allah; peace be upon you, O Prophet, and the mercy of Allah and His blessings; peace be upon us and upon the righteous slaves of Allah. I bear witness that none has the right to be worshipped but Allah and I bear witness that Muhammad is His slave and Messenger). Seven phrases which are the greeting of the prayer.’”  

أَنَّ رَسُولَ اللَّهِ ﷺ خَطَبَنَا وَبَيَّنَ لَنَا سُنَّتَنَا وَعَلَّمَنَا صَلاَتَنَا فَقَالَ إِذَا صَلَّيْتُمْ فَكَانَ عِنْدَ الْقَعْدَةِ فَلْيَكُنْ مِنْ أَوَّلِ قَوْلِ أَحَدِكُمُ التَّحِيَّاتُ الطَّيِّبَاتُ الصَّلَوَاتُ لِلَّهِ السَّلاَمُ عَلَيْكَ أَيُّهَا النَّبِيُّ وَرَحْمَةُ اللَّهِ وَبَرَكَاتُهُ السَّلاَمُ عَلَيْنَا وَعَلَى عِبَادِ اللَّهِ الصَّالِحِينَ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَأَشْهَدُ أَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ سَبْعُ كَلِمَاتٍ هُنَّ تَحِيَّةُ الصَّلاَةِ  

“The Messenger of Allah ﷺ used to teach us the Tashah-hud as he used to teach us a Surah from the Qur’an: ‘Bismillahi wa Billahi; at-tahiyyatu lillahi was-salawatu wat-tayyibatu lillahi; as-salamu ‘alayka ayyuhan- Nabiyyu wa rahmatullahi wa barakatuhu; as-salamu ‘alayna wa ‘ala ‘ibadillahis-salihin. Ashhadu an la ilaha illallah wa ashhadu anna Muhammadan ‘abduhu wa rasuluhu. As’alu Allahal-jannah, wa a’udhu billahi minannar (In the name of Allah and by the grace of Allah. All compliments are due to Allah and all prayers and good words are due to Allah. Peace be upon you, O Prophet, and the mercy of Allah and His blessings; peace be upon us and upon the righteous slaves of Allah. I bear witness that none has the right to be worshipped but Allah and I bear witness that Muhammad is His slave and Messenger. I ask Allah for Paradise and I seek refuge with Allah from the Fire).’”  

كَانَ رَسُولُ اللَّهِ ﷺ يُعَلِّمُنَا التَّشَهُّدَ كَمَا يُعَلِّمُنَا السُّورَةَ مِنَ الْقُرْآنِ بِاسْمِ اللَّهِ وَبِاللَّهِ التَّحِيَّاتُ لِلَّهِ وَالصَّلَوَاتُ وَالطَّيِّبَاتُ لِلَّهِ السَّلاَمُ عَلَيْكَ أَيُّهَا النَّبِيُّ وَرَحْمَةُ اللَّهِ وَبَرَكَاتُهُ السَّلاَمُ عَلَيْنَا وَعَلَى عِبَادِ اللَّهِ الصَّالِحِينَ أَشْهَدُ أَنْ لاَ إِلَهَ إِلاَّ اللَّهُ وَأَشْهَدُ أَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ أَسْأَلُ اللَّهَ الْجَنَّةَ وَأَعُوذُ بِاللَّهِ مِنَ النَّارِ
