Sahih Bukhari Volume 2, Book 19, Hadith 1157

حَدَّثَنَا أَبُو النُّعْمَانِ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ أَيُّوبَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، رضى الله عنهما قَالَ رَأَيْتُ عَلَى عَهْدِ النَّبِيِّ صلى الله عليه وسلم كَأَنَّ بِيَدِي قِطْعَةَ إِسْتَبْرَقٍ، فَكَأَنِّي لاَ أُرِيدُ مَكَانًا مِنَ الْجَنَّةِ إِلاَّ طَارَتْ إِلَيْهِ، وَرَأَيْتُ كَأَنَّ اثْنَيْنِ أَتَيَانِي أَرَادَا أَنْ يَذْهَبَا بِي إِلَى النَّارِ فَتَلَقَّاهُمَا مَلَكٌ فَقَالَ لَمْ تُرَعْ خَلِّيَا عَنْهُ‏

Narrated By Nafi : Ibn 'Umar said, "In the life-time of the Prophet I dreamt that a piece of silk cloth was in my hand and it flew with me to whichever part of Paradise I wanted. I also saw as if two persons (i.e. angels) came to me and wanted to take me to Hell. Then an angel met us and told me not to be afraid. He then told them to leave me.
