Sahih Bukhari Volume 2, Book 19, Hadith 1122

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، قَالَ حَدَّثَنَا هِشَامٌ، قَالَ أَخْبَرَنَا مَعْمَرٌ،‏.‏ وَحَدَّثَنِي مَحْمُودٌ، قَالَ حَدَّثَنَا عَبْدُ الرَّزَّاقِ، قَالَ أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ سَالِمٍ، عَنْ أَبِيهِ ـ رضى الله عنه ـ قَالَ كَانَ الرَّجُلُ فِي حَيَاةِ النَّبِيِّ صلى الله عليه وسلم إِذَا رَأَى رُؤْيَا قَصَّهَا عَلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَتَمَنَّيْتُ أَنْ أَرَى رُؤْيَا فَأَقُصَّهَا عَلَى رَسُولِ اللَّهِ صلى الله عليه وسلم وَكُنْتُ غُلاَمًا شَابًّا، وَكُنْتُ أَنَامُ فِي الْمَسْجِدِ عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم فَرَأَيْتُ فِي النَّوْمِ كَأَنَّ مَلَكَيْنِ أَخَذَانِي فَذَهَبَا بِي إِلَى النَّارِ فَإِذَا هِيَ مَطْوِيَّةٌ كَطَىِّ الْبِئْرِ، وَإِذَا لَهَا قَرْنَانِ، وَإِذَا فِيهَا أُنَاسٌ قَدْ عَرَفْتُهُمْ فَجَعَلْتُ أَقُولُ أَعُوذُ بِاللَّهِ مِنَ النَّارِ ـ قَالَ ـ فَلَقِيَنَا مَلَكٌ آخَرُ فَقَالَ لِي لَمْ تُرَعْ‏

Narrated By Salim's father : In the life-time of the Prophet whosoever saw a dream would narrate it to Allah's Apostle. I had a wish of seeing a dream to narrate it to Allah's Apostle (p.b.u.h) I was a grown up boy and used to sleep in the Mosque in the life-time of the Prophet. I saw in the dream that two angels caught hold of me and took me to the Fire which was built all round like a built well and had two poles in it and the people in it were known to me. I started saying, "I seek refuge with Allah from the Fire." Then I met another angel who told me not to be afraid.
