حَدَّثَنَا عَلِيُّ بْنُ حُجْرٍ، قَالَ حَدَّثَنَا إِسْمَاعِيلُ بْنُ جَعْفَرٍ، عَنْ حُمَيْدٍ، عَنْ أَنَسٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ دَخَلْتُ الْجَنَّةَ فَإِذَا أَنَا بِقَصْرٍ مِنْ ذَهَبٍ فَقُلْتُ لِمَنْ هَذَا الْقَصْرُ قَالُوا لِشَابٍّ مِنْ قُرَيْشٍ فَظَنَنْتُ أَنِّي أَنَا هُوَ فَقُلْتُ وَمَنْ هُوَ فَقَالُوا عُمَرُ بْنُ الْخَطَّابِ . هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
Narrated Anas: that the Prophet (ﷺ) said: "I entered Paradise and it was as if I was in a palace of gold. So I said: 'Whose palace is this?' They said: 'A youth's, from the Quraish.' So I thought that I was him. I said: 'And who is he?' They said: "'Umar bin Al-Khattab."
