Sahih al-Bukhari 6096
Narrated Samura bin Jundub:
The Prophet (ﷺ) said, "I saw (in a dream), two men came to me." Then the Prophet (ﷺ) narrated the story 
(saying), "They said, 'The person, the one whose cheek you saw being torn away (from the mouth to 
the ear) was a liar and used to tell lies and the people would report those lies on his authority till they 
spread all over the world. So he will be punished like that till the Day of Resurrection."'
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا جَرِيرٌ، حَدَّثَنَا أَبُو رَجَاءٍ، عَنْ سَمُرَةَ بْنِ جُنْدُبٍ ـ رضى الله عنه ـ قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏
"‏ رَأَيْتُ رَجُلَيْنِ أَتَيَانِي قَالاَ الَّذِي رَأَيْتَهُ يُشَقُّ شِدْقُهُ فَكَذَّابٌ يَكْذِبُ بِالْكَذْبَةِ تُحْمَلُ عَنْهُ حَتَّى تَبْلُغَ الآفَاقَ فَيُصْنَعُ بِهِ إِلَى يَوْمِ الْقِيَامَةِ ‏"‏‏.‏
