صحیح بخاری · Hadith 4730

Narrated Abu Sa`id Al-Khudri: Allah's Messenger said, "On the Day of Resurrection Death will be brought forward in the shape of a black and white ram. Then a call maker will call, 'O people of Paradise!' Thereupon they will stretch their necks and look carefully. The caller will say, 'Do you know this?' They will say, 'Yes, this is Death.' By then all of them will have seen it. Then it will be announced again, 'O people of Hell !' They will stretch their necks and look carefully. The caller will say, 'Do you know this?' They will say, 'Yes, this is Death.' And by then all of them will have seen it. Then it (that ram) will be slaughtered and the caller will say, 'O people of Paradise! Eternity for you and no death O people of Hell! Eternity for you and no death."' Then the Prophet, recited:-- 'And warn them of the Day of distress when the case has been decided, while (now) they are in a state of carelessness (i.e. the people of the world) and they do not believe.' (19.39)
