عَنِ الْمُغِيرَةِ بْنِ شُعْبَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ مَنْ حَدَّثَ بِحَدِيثٍ وَهُوَ يَرَى أَنَّهُ كَذِبٌ فَهُوَ أَحَدُ الْكَاذِبَيْنِ وَقَالَ عَبْدُ الرَّحْمَنِ فَهُوَ أَحَدُ الْكَذَّابَيْنِ
Narrated by Sayyiduna Mughirah bin Shu’bah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Whoever relates something, while he thinks it is a lie, then he will be counted as one of the two liars.
