3/38. Chapter:
The sin of a person who tells a lie against the Prophet (saws)
Sahih Bukhari
حَدَّثَنَا عَلِيُّ بْنُ الْجَعْدِ، قَالَ أَخْبَرَنَا شُعْبَةُ، قَالَ أَخْبَرَنِي مَنْصُورٌ، قَالَ سَمِعْتُ رِبْعِيَّ بْنَ حِرَاشٍ، يَقُولُ سَمِعْتُ عَلِيًّا، يَقُولُ قَالَ النَّبِيُّ صلى الله عليه وسلم " لاَ تَكْذِبُوا عَلَىَّ، فَإِنَّهُ مَنْ كَذَبَ عَلَىَّ فَلْيَلِجِ النَّارَ ".
Narrated `Ali: The Prophet (ﷺ) said, "Do not tell a lie against me for whoever tells a lie against me (intentionally) then he will surely enter the Hell-fire."
