Ribʿī b. Ḥirāsh heard Alī giving a khuṭbah and he said that the Messenger of Allah ﷺ said, "Do not lie upon me; indeed whoever lies upon me will enter the Fire."
أَنَّهُ سَمِعَ عَلِيًّا ؓ يَخْطُبُ قَالَ: قَالَ رَسُولُ اللَّهِ ﷺ «لاَ تَكْذِبُوا عَلَىَّ فَإِنَّهُ مَنْ يَكْذِبْ عَلَىَّ يَلِجِ النَّارَ۔»
