عَنْ قَيْسِ بْنِ سَعْدِ بْنِ عُبَادَةَ الْأَنْصَارِيِّ رَضِيَ اللَّهُ عَنْهُ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقُولُ ((مَنْ كَذَبَ عَلَيَّ كِذْبَةً مُتَعَمِّدًا فَلْيَتَبَوَّأْ مَضْجَعًا مِنَ النَّارِ أَوْ بَيْتًا فِي جَهَنَّمَ))
Narrated by Sayyiduna Qais bin Sa'd bin Ubadah Ansari (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Whoever deliberately tells a lie about me once, then let him prepare his abode in the Fire or his house in Hell.
