Sunan Ibn Majah, Hadith 32

It was narrated that Anas bin Malik said: "The Messenger of Allah said: 'Whoever tells lies about me', I (the narrator) think that he also said 'deliberately', let him take his place in Hell.'"

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 ‏" ‏ ‏.‏
