Narrated Abu Huraira: While we were sitting with Allah's Messenger, (he) Allah's Messenger (ﷺ) said, "While I was sleeping, I saw a woman performing ablution beside a palace. I asked, "Whose palace is this?' It was said, 'This palace belongs to `Umar.' Then I remembered his sense of Ghira and returned." On that `Umar started weeping in that gathering and said, "O Allah's Messenger! How dare I think of my self-respect being offended by you?"

حَدَّثَنَا عَبْدَانُ، أَخْبَرَنَا عَبْدُ اللَّهِ، عَنْ يُونُسَ، عَنِ الزُّهْرِيِّ، قَالَ أَخْبَرَنِي ابْنُ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ بَيْنَمَا نَحْنُ عِنْدَ رَسُولِ اللَّهِ صلى الله عليه وسلم جُلُوسٌ، فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " بَيْنَمَا أَنَا نَائِمٌ رَأَيْتُنِي فِي الْجَنَّةِ، فَإِذَا امْرَأَةٌ تَتَوَضَّأُ إِلَى جَانِبِ قَصْرٍ، فَقُلْتُ لِمَنْ هَذَا قَالَ هَذَا لِعُمَرَ. فَذَكَرْتُ غَيْرَتَهُ فَوَلَّيْتُ مُدْبِرًا ". فَبَكَى عُمَرُ وَهْوَ فِي الْمَجْلِسِ ثُمَّ قَالَ أَوَعَلَيْكَ يَا رَسُولَ اللَّهِ أَغَارُ.
