Sahih Bukhari Volume 8, Book 76, Hadith Number 550.

Narated By Abu Huraira : I heard Allah’s Apostle saying, “From my followers there will enter Paradise a crowd, seventy thousand in number whose faces will glitter as the moon does when it is full.” On hearing that, ‘Ukasha bin Mihsan Al-Asdi got up, lifting his covering sheet, and said, “O Allah’s Apostle! Invoke Allah that He may make me one of them.” The Prophet said, “O Allah, make him one of them.” Another man from the Ansar got up and said, “O Allah’s Apostle! Invoke Allah to make me one of them. “The Prophet said (to him), “‘Ukasha has preceded you.”
