16يَومَ نَبطِشُ البَطشَةَ الكُبرىٰ إِنّا مُنتَقِمونَAli UnalOn the day when We will seize with the mightiest grasp,1 We will indeed take retribution.The verses flow in such a way that the “smoke” is indicated in all the meanings mentioned above in note 3. So the day mentioned in this verse and the seizure may well be referring to the Battle of Makkah, where almost all the leading enemies of the Messenger, upon him be peace and blessings, were killed; as well as to the greatest calamities and wars that will occur toward the end of time; and finally, to Judgment Day, when the unbelievers will be thrown into Hell.
