Ola-ika allatheena kafaroo bi-ayati rabbihim waliqa-ihi fahabitat aAAmaluhum fala nuqeemu lahum yawma (surah Kahf: 105)

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

(18:105) those are the people who rejected the Signs of their Lord and did not believe that they would ever go before Him. Therefore all their deeds were lost, for We will assign no weight to them on the Day of Resurrection. *77

Ulaaa`ikal lazeena kafaroo bi aayaati Rabbihim wa liqaaa`ihee fahabitat a`maaluhum falaa nuqeemu lahum Yawmal Qiyaamati waznaa

*77) "All their deeds were lost" in the sense that they will be of no avail to them in the life-after-death, even though they might have considered them as their great achievements but the fact is that they will lose all their value as soon as the world shall come to an end. When they will go before their Lord, and all their deeds shall be placed in the Scales, they will have no weight at all whether they had built great palaces, established great universities and libraries, set up great factories and laboratories, constructed highways and railways, in short, all their inventions, industries, sciences and arts and other things of which they were very proud in this world, will lose their weights in the Scales. The only thing which will have weight there will be that which had been done in accordance with the Divine instructions and with the intention to please AIIah. It is, therefore, obvious that if all of one's endeavours were confined to the worldly things and the achievement of worldly desires whose results one would see in this world, one should not reasonably expect to see their results in the Hereafter, for they would have gone waste with the end of this world. It is equally obvious, that only the deeds of the one, who performed them strictly in accordance with His instructions to win His approval with a view to avail of their results in the Hereafter, will find that his deeds had weight in the Scales. On the contrary, such a one will find that all his endeavours in the world had gone waste.
