Narrated Abu Sa`id Al-Khudri:

Allah's Messenger (ﷺ) 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)

Abu Sa'id reported Allah's Messenger (ﷺ) as saying: Death would be brought on the Day of Resurrection. in the form of a white-coloured ram. Abu Kuraib made this addition: Then it would be made to stand between the Paradise and the Hell. So far as the rest of the hadith is concerned there is perfect agreement (between the two narrators) and it would be said to the inmates of Paradise: Do you recognise this? They would raise up their necks and look towards it and say: Yes, ' it is death. Then it would be said to the inmates of Hell-Fire.. Do you recognise this? And they would raise up their necks and look and say: Yes, it is death. Then command would be given for slaughtering that and then it would be said: 0 inmates of Paradise,, there is an everlasting life for you and no death. And then (addressing) to the inmates of the Hell-Fire, it would be said: 0 inmates of Hell-Fire, there is an everlasting living for you and no death. Allah's Messenger (may peace be u@on him) then recited this verse pointing with his hand to this (material) world:" Warn them, this Day of dismay, and when their affairs would be decided and they would be un- mindful and they believe not" (xix. 39).
