What did the Prophet Muhammad (saw) have to say about `Umar's sense of Ghira when he saw a dream?
 Narrated Abu Huraira:                     While we were sitting with Allah's Apostle, (he) Allah's Apostle 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 Apostle! How dare I think of my self-respect being offended by you?"
