The Messenger of Allah (ﷺ) taught me tashahhud taking my hand within his palms, in the same way as he taught me a Sura of the Quran, and he narrated it as narrated above.
Sahih Muslim Book 4, Hadith 63
← Previous Hadith We were sitting with the Apostle (ﷺ) in prayer, and the rest of the hadith is the same as narrated by Mansur He (also said): After (reciting tashahud) he may choose any prayer.

Sahih Muslim Book 4, Hadith 62 Next Hadith → The Messenger of Allah (ﷺ) used to teach us tashahhud just as he used to teach us a Surah of the Quran, and he would say: All services rendered by words, acts of worship, and all good things are due to Allah. Peace be upon you, O Prophet, and Allah's mercy and blessings. Peace be upon us and upon Allah's upright servants. I testify that there is no god but Allah, and I testify that Muhammad is the Messenger of Allah. In the narration of Ibn Rumh (the words are): "As he would teach us the Quran."
