From Sahih Bukhari (Hadith 5227):
Narrated Abu Huraira:While we were sitting with Allah's Messenger (ﷺ), (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 (ﷺ)! How dare I think of my self-respect being offended by you?
