(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!

"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).
