Narrated Abu Sa'eed Al-Khudri: "The Messenger of Allah (ﷺ) recited: And warn them of a Day of griefs and regrets (19:39) and he said: 'Death will be brought as if it is a mixed black and white ram, until it is halted upon the barrier between Paradise and the Fire. It will be said: 'O people of Paradise! They will raise up their necks to look. It will be said: 'O people of the Fire! And they will raise up their necks to look. It will be said: 'Do you recognize this?' They will say: 'Yes. This is death.' Then it will be laid down and slaughtered. If it were not that Allah had decreed that the inhabitants of Paradise would remain, then they would die of joy, and if it were not that Allah had decreed that the inhabitants of the Fire would remain, then they would die of grief.'"
