Sahih Bukhari Volume 6, Book 60, Hadith Number 264.

Narrated By Ibn Abbas : The Prophet delivered a sermon and said, “You (people) will be gathered before Allah (on the Day of Resurrection) bare-footed, naked and uncircumcised.” (The Prophet then recited): ‘As We began the first creation We shall repeat it. (It is) a promise We have undertaken and truly We shall do it.’ and added, “The first man who will be dressed on the Day of Resurrection, will be Abraham. Lo! Some men from my followers will be brought and taken towards the left side, whereupon I will say, ‘O Lord, (these are) my companions!’ It will be said, ‘You do not know what new things they introduced (into the religion) after you.’ I will then say as the righteous pious slave, Jesus, said, ‘I was a witness over them while I dwelt among them… (to His Statement)… and You are the Witness to all things.’ (5.117) Then it will be said, ‘(O Muhammad) These people never stopped to apostate since you left them.”
