Abu Dawud Book 25, Hadith Number 3976.

Narated By Abu Sa’id al-Khudri : The Prophet (PBUH) said: A man from the ‘illiyyun will look downwards at the people of Paradise and Paradise will be glittering as if it were a brilliant star.

He (the narrator) said: In this way the word durri (brilliant) occurs in this tradition, i.e. the letter dal (d) has short vowel u and it has no hamzah (‘). Abu Bakr and ‘Umar will be of them and will have some additional blessings.
