Sahih Bukhari Volume 008, Book 076, Hadith Number 587.

Narated By Abu Huraira : The Prophet said, "While I was sleeping, a group (of my followers were brought close to me), and when I recognized them, a man (an angel) came out from amongst (us) me and them, he said (to them), 'Come along.' I asked, 'Where?' He said, 'To the (Hell) Fire, by Allah' I asked, 'what is wrong with them' He said, 'They turned apostate as renegades after you left.' Then behold! (Another) group (of my followers) were brought close to me, and when I recognized them, a man (an angel) came out from (me and them) he said (to them); Come along.' I asked, "Where?' He said, 'To the (Hell) Fire, by Allah.' I asked, What is wrong with them?' He said, 'They turned apostate as renegades after you left. So I did not see anyone of them escaping except a few who were like camels without a shepherd."
