Almuntakhab Fi Tafsir Alquran Alkarim

How vainly did he rejoice among his people before and disregarded the concord of this discord

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

(84:13) He used to live joyfully among his people, *9

Indeed, he had [once] been among his people in happiness; meaning

*9) That is, his way of life was different from that of God's righteous men, about whom in Surah At-Tur: 26, it has been said that they lived among their kinsfolk in fear and dread of God, i.e. they fear lest they should ruin their own Hereafter on account of their absorption in the love of children and endeavours for the sake of their well-being and prosperity in the world. On the contrary, this tnan lived a life free from every care and worry and helped his children and kinsfolk also to enjoy life fully, no matter what wicked and inunoral methods he had to use to procure the means of enjoyment, how he had to usurp the rights of others and transgress the bounds set by AIIah for the sake of the worldly pleasures.
