وَعَن سَمُرَة بن جُنْدُب وَالْمُغِيرَةِ بْنِ شُعْبَةَ
قَالَا: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ حَدَّثَ عَنِّي بِحَدِيثٍ يَرَى أَنَّهُ كَذِبٌ فَهُوَ أَحَدُ الْكَاذِبِينَ»
Samurah ibn Jundub and Al-Mughirah ibn Shubah reported God’s messenger as saying, “If anyone relates a tradition from me thinking that it is false, he is one of the liars.”
