Sahih Bukhari Volume 9, Book 91, Hadith 7027

حَدَّثَنِي يَحْيَى بْنُ بُكَيْرٍ، حَدَّثَنَا اللَّيْثُ، عَنْ عُقَيْلٍ، عَنِ ابْنِ شِهَابٍ، أَخْبَرَنِي سَعِيدُ بْنُ الْمُسَيَّبِ، أَنَّ أَبَا هُرَيْرَةَ، قَالَ بَيْنَمَا نَحْنُ جُلُوسٌ عِنْدَ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ بَيْنَا أَنَا نَائِمٌ رَأَيْتُنِي فِي الْجَنَّةِ، فَإِذَا امْرَأَةٌ تَتَوَضَّأُ إِلَى جَانِبِ قَصْرٍ، فَقُلْتُ لِمَنْ هَذَا الْقَصْرُ فَقَالُوا لِعُمَرَ‏.‏ فَذَكَرْتُ غَيْرَتَهُ فَوَلَّيْتُ مُدْبِرًا ‏"‏‏.‏ فَبَكَى عُمَرُ وَقَالَ عَلَيْكَ بِأَبِي أَنْتَ وَأُمِّي يَا رَسُولَ اللَّهِ أَغَارُ ؟

Narrated By Abu Huraira : We were sitting with Allah's Apostle he said, "While I was sleeping, I saw myself in Paradise, and behold, a woman was performing ablution by the side of a palace. I asked, 'For whom is this palace?' They replied, 'For 'Umar' Then I remembered the Ghira of 'Umar and returned immediately." 'Umar wept (on hearing that) and said, "Let my father and mother be sacrificed for you, O Allah's Apostle! How dare I think of my Ghira being offended by you."
