Almuntakhab Fi Tafsir Alquran Alkarim

Those infidels, who deny Allah, whose physical and mental efforts are not intimately mixed with the spiritual apprehension of divine truths were born to be losers. Their efforts are useless and stand similitude exact of ashes which are exposed to violent high winds scattering them in all directions. They are unable to advantage themselves of what they have accomplished, and this is perversion in the extreme

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

The example of those who disbelieve in their Lord is [that] their meaning

*25) That is, "Those who were perfidious, faithless, and disobedient to the Divine Message, and refused to adopt that Way to which the Messengers invited, will find in the end that all the deeds and earnings of their lives were as worthless as a heap of ashes. Just as each and every particle of a high mound of ashes formed during a long course of years is scattered by the wind on a stormy day, likewise all their grand works will prove on the stormy Doomsday to be no more than a mound of ashes. Their dazzling culture, their grand civilization, their wonderful kingdoms and states, their magnificent universities, their sciences and their literatures, nay, even their hypocritical worship, and so-called virtuous deeds, their charitable and reformative works of which they were very proud in the worldly lift, shall prove to be as worthless as a heap of ashes, and will be scattered by the "Storm" of the Day of Resurrection. So much so that there shall not remain a single particle of their works worthy of being placed in the Divine scale on that Day in their favour.
