Narrated Ibn `Umar: The Prophet (peace be upon him); said,
“The people of Paradise will enter Paradise, and the people of the (Hell) Fire will enter the (Hell) Fire: then a call-maker will get up (and make an announcement) among them, ‘O the people of the (Hell) Fire! No death anymore! And O people of Paradise! No death (anymore) but Eternity.”
Sahih al-Bukhari, Vol.8, Book 81, Hadith 133
