(69) بَابُ قَوْلِ اللَّهِ تَعَالَى: {يَا أَيُّهَا الَّذِينَ آمَنُوا اتَّقُوا اللَّهَ وَكُونُوا مَعَ الصَّادِقِينَ} وَمَا يُنْهَى عَنِ الْكَذِبِ
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."'
