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)

“The Messenger of Allah (ﷺ) said: ‘When Allah gathers all creatures on the Day of Resurrection, permission will be given to the nation of Muhammad to prostrate, so they will prostrate to Him for a long time. Then it will be said: “Raise your heads, for a certain number of you will go to Hell-fire and these will be your ransom from Hell.”*

We came upon `Abdullah bin Mas`ud and he said "O people! If somebody knows something, he can say it, but if he does not know it, he should say, "Allah knows better,' for it is a sign of having knowledge to say about something which one does not know, 'Allah knows better.' Allah said to His Prophet: 'Say (O Muhammad ! ) No wage do I ask of You for this (Qur'an) nor am I one of the pretenders (a person who pretends things which do not exist).' (38.86) Now I will tell you about Ad- Dukhan (the smoke), Allah's Messenger (ﷺ) invited the Quraish to embrace Islam, but they delayed their response. So he said, "O Allah! Help me against them by sending on them seven years of famine similar to the seven years of famine of Joseph." So the famine year overtook them and everything was destroyed till they ate dead animals and skins. People started imagining to see smoke between them and the sky because of severe hunger. Allah said: 'Then watch you for the Day that the sky will bring forth a kind of smoke plainly visible, covering the people. . . This is painful torment.' (44.10-11) (So they invoked Allah) "Our Lord! Remove the punishment from us really we are believers." How can there be an (effectual) reminder for them when an Apostle, explaining things clearly, has already come to them? Then they had turned away from him and said: 'One taught (by a human being), a madman?' 'We shall indeed remove punishment for a while, but truly, you will revert (to disbelief).' (44.12-15) Will the punishment be removed on the Day of Resurrection?" `Abdullah added, "The punishment was removed from them for a while but they reverted to disbelief, so Allah destroyed them on the Day of Badr. Allah said: 'The day We shall seize you with a mighty grasp. We will indeed (then) exact retribution." (44.16)

Some of the people of Shirk came to Muhammad and said: "What you say and call people to is good, if only you could tell us that there is any expiation for what we have done." Then the Verses: "And those who invoke not any other ilah (god) along with Allah, or kill such a person as Allah has forbidden, except by right." And "Say: O 'Ibadi (My slaves) who have transgressed against themselves (by committing evil deeds and sins)" were revealed.

I heard the Prophet (ﷺ) reciting when on the pulpit: 'They will cry, "O Malik (Keeper of Hell) Let your Lord make an end of us.' (43.77)
