[Machine] The Prophet ﷺ used to teach us the tashahhud, just as he would teach us a Surah from the Quran, and he would say, "Learn it, for there is no prayer without the tashahhud."
كَانَ النَّبِيُّ ﷺ يُعَلِّمُنَا التَّشَهُّدَ كَمَا يُعَلِّمُنَا السُّورَةَ مِنَ الْقُرْآنِ وَيَقُولُ «تَعَلَّمُوا؛ فَإِنَّهُ لَا صَلَاةَ إِلَّا بِالتَّشَهُّدِ»
