He who narrated (a Hadith) from the Messenger of Allah (saws) when he considers it to be false
Sunan Ibn Majah
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا وَكِيعٌ، عَنْ سُفْيَانَ، عَنْ حَبِيبِ بْنِ أَبِي ثَابِتٍ، عَنْ مَيْمُونِ بْنِ أَبِي شَبِيبٍ، عَنِ الْمُغِيرَةِ بْنِ شُعْبَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " مَنْ حَدَّثَ عَنِّي بِحَدِيثٍ وَهُوَ يَرَى أَنَّهُ كَذِبٌ فَهُوَ أَحَدُ الْكَاذِبَيْنِ " .
It was narrated that Mughirah bin Shu'bah said: The Messenger of Allah (ﷺ) said: '"Whoever narrates a Hadith from me thinking it to be false, then he is one of the two liars."
