سُنَنُ ابْنِ مَاجَهْ
Sunan Ibn Majah 32
The Book of the Sunnah
Severe condemnation of deliberately telling lies against the Messenger of Allah (ﷺ)
حَدَّثَنَا مُحَمَّدُ بْنُ رُمْحٍ الْمِصْرِيُّ، حَدَّثَنَا اللَّيْثُ بْنُ سَعْدٍ، عَنِ ابْنِ شِهَابٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ مَنْ كَذَبَ عَلَىَّ - حَسِبْتُهُ قَالَ مُتَعَمِّدًا - فَلْيَتَبَوَّأْ مَقْعَدَهُ مِنَ النَّارِ .
It was narrated that Anas bin Malik said: "The Messenger of Allah (ﷺ) said: 'Whoever tells lies about me', I (the narrator) think that he also said 'deliberately', let him take his place in Hell.'"
