Overall meaning : The Almighty says: The idolaters among your people, Muhammad, ask you to hasten on Allah’s punishment for them, of which he has warned them. Had it not been for Allah’s decree to inflict punishment on them at a time He has already appointed, it would have come upon them at once. Indeed, it will come down upon them suddenly and catch them unawares, when they least expect it.
The idolaters among your people ask you to hasten on Allah’s punishment for them, but Hell will encompass them and all unbelievers on the day when the punishment of the Fire will overwhelm them from above them and from beneath their feet; and Allah will say to the unbelievers, ‘Taste now the punishment for what you used to do in the worldly life.’
