" On the day when they are dragged into the Fire upon their faces, taste the touch of Fire. Surely, We have created everything according to a measure" (liv. 48).

"Indeed a disbeliever's skin will be forty-two forearm lengths thick, his molar teeth will be like Uhud (mountain), and his sitting place in Hell will be like what is between Makkah and Al-Madinah."

"The idolators and Quraish came and disputed with the Prophet (ﷺ) concerning the Divine Decree. Then the following verse was revealed: 'The Day they will be dragged on their faces into the Fire (it will be said to them): "Taste you the touch of Hell!" Verily We have created all things with Qadar. (Divine Decree)'"

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.

The molar tooth of an unbeliever or the canine teeth of an unbeliever will be like Uhud and the thickness of his skin a three night's journey.
