وَعَن عمر قَالَ: قَامَ فِينَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَقَامًا فَأَخْبَرَنَا عَنْ بَدْءِ الْخَلْقِ حَتَّى دَخَلَ أَهْلُ الْجَنَّةِ مَنَازِلَهُمْ وَأَهْلُ النَّارِ مَنَازِلَهُمْ حَفِظَ ذَلِكَ مَنْ حَفِظَهُ وَنَسِيَهُ مَنْ نسيَه ". رَوَاهُ البُخَارِيّ
`Umar told that God's messenger stood up among them and told them about the beginning of creation up to the time when the inhabitants of paradise will enter their abodes and the inhabitants of hell will enter theirs, saying that some remembered that and others forgot. Bukhari transmitted it.
