that the Prophet ﷺ said: "Beware of narrating from me except what I taught you, for whoever lies about me on purpose, then let him take his seat in the Fire. And whoever says (something) about the Qur'an according to his (own) opinion, then let him take his seat in the Fire."
عَنِ النَّبِيِّ ﷺ قَالَ اتَّقُوا الْحَدِيثَ عَنِّي إِلاَّ مَا عَلِمْتُمْ فَمَنْ كَذَبَ عَلَىَّ مُتَعَمِّدًا فَلْيَتَبَوَّأْ مَقْعَدَهُ مِنَ النَّارِ وَمَنْ قَالَ فِي الْقُرْآنِ بِرَأْيِهِ فَلْيَتَبَوَّأْ مَقْعَدَهُ مِنَ النَّارِ
