Sahih Bukhari | Volume 9 | Hadith Number 151

Narrated by Jabir bin 'Abdullah
Allah's Apostle said: (I saw in a dream that) I entered Paradise, and behold, there was a palace built of gold! I asked, 'For whom is this palace?' They (the angels) replied, 'For a man from the Quraish.' " The Prophet added, "O Ibn Al-Khattab! Nothing stopped me from entering it except your Ghira." 'Umar said, "How dare I think of my Ghira being offended by you, O Allah's Apostle?"
