Sunan Ibn Majah Book 0, Hadith 107

حَدَّثَنَا مُحَمَّدُ بْنُ الْحَارِثِ الْمِصْرِيُّ، أَنْبَأَنَا اللَّيْثُ بْنُ سَعْدٍ، حَدَّثَنِي عُقَيْلٌ، عَنِ ابْنِ شِهَابٍ، أَخْبَرَنِي سَعِيدُ بْنُ الْمُسَيَّبِ، أَنَّ أَبَا هُرَيْرَةَ، قَالَ كُنَّا جُلُوسًا عِنْدَ النَّبِيِّ ـ صلى الله عليه وسلم ـ قَالَ ‏ "‏ بَيْنَا أَنَا نَائِمٌ رَأَيْتُنِي فِي الْجَنَّةِ فَإِذَا أَنَا بِامْرَأَةٍ تَتَوَضَّأُ إِلَى جَانِبِ قَصْرٍ فَقُلْتُ لِمَنْ هَذَا الْقَصْرُ فَقَالَتْ لِعُمَرَ ‏.‏ فَذَكَرْتَ غَيْرَتَهُ فَوَلَّيْتُ مُدْبِرًا ‏"‏ ‏.‏ قَالَ أَبُو هُرَيْرَةَ فَبَكَى عُمَرُ فَقَالَ أَعَلَيْكَ بِأَبِي وَأُمِّي يَا رَسُولَ اللَّهِ أَغَارُ

Abu Hurairah said:"We were sitting with the Prophet and he said: 'While I was sleeping I saw myself in Paradise (in a dream), and I saw a woman performing ablution beside a palace. I asked: "Whose palace is this?" She said: "'Umar's." I remembered his protective jealousy, so I turned away and left.'" Abu Hurairah said: ''Umar wept and said: 'May my father and mother be sacrificed for you, O Messenger of Allah! Would I feel any protective jealousy against you?
