ভূমিকা
Verily We have prepared Hell for the infidels to be entertained (therein).” This holy verse has pointed to a mental deviation of those people. It had been the main origin of their other aberrations. It says: “Do then those who disbelieve think that they can take My servants as guardians besides Me?…” Have these servants, such as Messiah (as) and the angels, who were worshipped, howsoever much their ranks may be high, any thing from themselves that can support others?
Or, on the contrary, whatever they had were given them from the side of Allah. They themselves needed to be guided by the guidance of Allah, too. This is a fact that those people forgot and, therefore, sunk into disbelief.
“Those whose effort is lost in this world’s life, while they think that they are working good deeds.” This verse, as well as the other verses up to the end of Surah Al-Kahf, not only is an explanation upon the qualities of the faithless persons, but also is a kind of summary for all the subjects which were discussed in this Surah. They are especially the matters concerning the story of the of the Cave, Moses, Khidr, Zul-Qarnayn and their efforts and struggles against their opponents.
At first, it refers to the greatest losers, the most wretched persons among all mankind.
