Hadith 3:51
Narrated Salama:
I heard the Prophet (ﷺ) saying, "Whoever (intentionally) ascribes to me what I have not said then (surely) let him occupy his seat in Hell-fire."
حَدَّثَنَا مَكِّيُّ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا يَزِيدُ بْنُ أَبِي عُبَيْدٍ، عَنْ سَلَمَةَ، قَالَ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ " مَنْ يَقُلْ عَلَىَّ مَا لَمْ أَقُلْ فَلْيَتَبَوَّأْ مَقْعَدَهُ مِنَ النَّارِ "
