حَدَّثَنَا سُوَيْدُ بْنُ سَعِيدٍ، حَدَّثَنَا عَلِيُّ بْنُ مُسْهِرٍ، عَنْ مُطَرِّفٍ، عَنْ عَطِيَّةَ، عَنْ أَبِي سَعِيدٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " مَنْ كَذَبَ عَلَىَّ مُتَعَمِّدًا فَلْيَتَبَوَّأْ مَقْعَدَهُ مِنَ النَّارِ " .
It was narrated from Abu Sa'eed said: "The Messenger of Allah (ﷺ) said: 'Whoever tells lies about me deliberately, let him take his place in Hell."
