Sahih Bukhari Volume 5, Book 64, Hadith 4376

قَالَ ابْنُ عَبَّاسٍ فَسَأَلْتُ عَنْ قَوْلِ، رَسُولِ اللَّهِ صلى الله عليه وسلم ‏"‏ إِنَّكَ أُرَى الَّذِي أُرِيتُ فِيهِ مَا أُرِيتُ ‏"‏‏.‏ فَأَخْبَرَنِي أَبُو هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ بَيْنَا أَنَا نَائِمٌ رَأَيْتُ فِي يَدَىَّ سِوَارَيْنِ مِنْ ذَهَبٍ، فَأَهَمَّنِي شَأْنُهُمَا، فَأُوحِيَ إِلَىَّ فِي الْمَنَامِ أَنِ انْفُخْهُمَا، فَنَفَخْتُهُمَا فَطَارَا فَأَوَّلْتُهُمَا كَذَّابَيْنِ يَخْرُجَانِ بَعْدِي، أَحَدُهُمَا الْعَنْسِيُّ، وَالآخَرُ مُسَيْلِمَةُ ‏"‏‏.‏

I asked about the statement of Allah's Apostle : "You seem to be the same person who was shown to me in my dream," and Abu Huraira informed me that Allah's Apostle said, "When I was sleeping, I saw (in a dream) two bangles of gold on my hands and that worried me. And then I was inspired Divinely in the dream that I should blow on them, so I blew on them and both the bangles flew away. And I interpreted it that two liars (who would claim to be prophets) would appear after me. One of them has proved to be Al Ansi and the other, Musailima."
