Sahih al-Bukhari Book 65, Hadith 251
Allah's Messenger (ﷺ) said, "On the Day of Resurrection, a huge fat man will come who will not weigh, the
weight of the wing of a mosquito in Allah's Sight." and then the Prophet (ﷺ) added, 'We shall not give
them any weight on the Day of Resurrection ' (18.105)
I asked my father, "Was the Verse:-- 'Say: (O Muhammad) Shall We tell you the greatest losers in respect of their deeds?'(18.103) revealed regarding Al-Haruriyya?" He said, "No, but regarding the Jews and the Christians, for the Jews disbelieved Muhammad and the Christians disbelieved in Paradise and say that there are neither meals nor drinks therein. Al- Hururiyya are those people who break their pledge to Allah after they have confirmed that they will fulfill it, and Sa`d used to call them 'Al-Fasiqin (evildoers who forsake Allah's obedience).
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)
