Sahih al-Bukhari Book 62, Hadith 30
While we were with Allah's Messenger (ﷺ) he said, "While I was sleeping, I saw myself in Paradise, and
suddenly I saw a woman performing ablution beside a palace. I asked, 'For whom is this palace?' They
replied, 'It is for `Umar.' Then I remembered `Umar's Ghira (self-respect) and went away quickly."
`Umar wept and said, O Allah's Messenger (ﷺ)! How dare I think of my ghira (self-respect) being offended
by you?
The Prophet (ﷺ) said, "I saw myself (in a dream) entering Paradise, and behold! I saw Ar-Rumaisa', Abu Talha's wife. I heard footsteps. I asked, Who is it? Somebody said, 'It is Bilal ' Then I saw a palace and a lady sitting in its courtyard. I asked, 'For whom is this palace?' Somebody replied, 'It is for `Umar.' I intended to enter it and see it, but I thought of your (`Umar's) Ghira (and gave up the attempt)." `Umar said, "Let my parents be sacrificed for you, O Allah's Messenger (ﷺ)! How dare I think of my Ghira (self-respect) being offended by you?
Allah's Messenger (ﷺ) said, "While I was sleeping, I saw myself drinking (i.e. milk), and I was so contented that I saw the milk flowing through my nails. Then I gave (the milk) to `Umar." They (i.e. the companions of the Prophet) asked, "What do you interpret it?" He said, "Knowledge."
