Dialects and Readings of the Qur'an (Kitab Al-Huruf Wa Al-Qira'at)
Dawud :: Book 30 : Hadith 3976
Narrated AbuSa'id al-Khudri:
The Prophet (peace_be_upon_him) 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 ('). AbuBakr and Umar will be of them and will have some additional blessings.
