Narrated Masruq:

While a man was delivering a speech in the tribe of Kinda, he said, "Smoke will prevail on the Day of Resurrection and will deprive the hypocrites their faculties of hearing and seeing. The believers will be afflicted with something like cold only thereof." That news scared us, so I went to (Abdullah) Ibn Mas`ud while he was reclining (and told him the story) whereupon he became angry, sat up and said, "He who knows a thing can say, it, but if he does not know, he should say, 'Allah knows best,' for it is an aspect of knowledge to say, 'I do not know,' if you do not know a certain thing. Allah said to His prophet. 'Say (O Muhammad): No wage do I ask of you for this (Qur'an), nor I am one of the pretenders (a person who pretends things which do not exist.)' (38.86) The Qur'aish delayed in embracing Islam for a period, so the Prophet (ﷺ) invoked evil on them, saying, 'O Allah! Help me against them by sending seven years of (famine) like those of Joseph.' So they were afflicted with such a severe year of famine that they were destroyed therein and ate dead animals and bones. They started seeing something like smoke between the sky and the earth (because of severe hunger). Abu Sufyan then came (to the Prophet) and said, "O Muhammad! You came to order us for to keep good relations with Kith and kin, and your kinsmen have now perished, so please invoke Allah (to relieve them).' Then Ibn Mas`ud recited:-- 'Then watch you for the day that the sky will bring forth a kind of smoke plainly visible....but truly you will return! (to disbelief) (44.10-15) Ibn Mas`ud added, Then the punishment was stopped, but truly, they reverted to heathenism (their old way). So Allah (threatened them thus): 'On the day when we shall seize you with a mighty grasp.' (44.16) And that was the day of the Battle of Badr. Allah's saying- "Lizama" (the punishment) refers to the day of Badr Allah's Statement: Alif-Lam-Mim, the Romans have been defeated, and they, after their defeat, will be victorious,' (30.1- 3) (This verse): Indicates that the defeat of Byzantine has already passed.

Narrated Masruq:

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)

Narrated `Abdullah:

It is a sign of having knowledge that, when you do not know something, you say: 'Allah knows better.' Allah said to his Prophet: 'Say: 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) When the Quraish troubled and stood against the Prophet (ﷺ) he said, "O Allah! Help me against them by afflicting them with seven years of famine like the seven years of Joseph." So they were stricken with a year of famine during which they ate bones and dead animals because of too much suffering, and one of them would see something like smoke between him and the sky because of hunger. Then they said: Our Lord! Remove the torment from us, really we are believers. (44.12) And then it was said to the Prophet (by Allah), "If we remove it from them. they will revert to their ways (of heathenism)." So the Prophet (ﷺ) invoked his Lord, who removed the punishment from them, but later they reverted (to heathenism), whereupon Allah punished them on the day of the Battle of Badr, and that is what Allah's Statement indicates: 'Then watch for the day that the sky will bring forth a kind of smoke plainly visible...we will indeed (then) exact retribution.' (44.10).

Narrated `Abdullah:

Allah sent (the Prophet) Muhammad and said:-- 'Say, No wage do I ask of you for this (Qur'an) nor am I one of the pretenders (i.e. a person who pretends things which do not exist). (38.68) When Allah's Messenger (ﷺ) saw Quraish standing against him, he said, "O Allah! Help me against them by afflicting them with seven years of famine similar to the seven years (of famine) of Joseph. So they were afflicted with a year of drought that destroyed everything, and they ate bones and hides. (One of them said), "And they ate hides and dead animals, and (it seemed to them that) something like smoke was coming out of the earth. So Abu Sufyan came to the Prophet (ﷺ) and said, "O Muhammad! Your people are on the verge of destruction! Please invoke Allah to relieve them." So the Prophet (ﷺ) invoked Allah for them (and the famine disappeared). He said to them. "You will revert (to heathenism) after that." `Abdullah then recited: 'Then watch you for the Day that the sky will bring forth a kind of smoke plainly visible.......but truly you will revert (to disbelief).' He added, "Will the punishment be removed from them in the Hereafter? The smoke and the grasp and the Al-Lizam have all passed." One of the sub-narrater said, "The splitting of the moon." And another said, "The defeat of the Romans (has passed).
