Narrated Abu Huraira:

We were sitting with Allah's Apostle, he said, "While I was sleeping, I saw myself in Paradise. Suddenly I saw a woman performing ablution beside a palace. I asked, "For whom is this palace?" They (the angels) replied, "It is for 'Umar bin Al-Khattab." Then I remembered 'Umar's ghira and went back hurriedly." On hearing that, 'Umar started weeping 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?
