Samura b. Jundub and al-Mughira b. Shu'ba reported God’s messenger as saying, “If anyone relates a tradition from me thinking that it is false, he is one of the liars.” Muslim transmitted it.

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» . رَوَاهُ مُسلم
