Almuntakhab Fi Tafsir Alquran Alkarim

But blessed, indeed, is he who vindicates his own wrongs and is kindly disposed to benevolence

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

(87:14) He who purified himself shall prosper, *13

He has certainly succeeded who purifies himself meaning

*13) "Who purified himself": who affirmed the faith giving up disbelief and polytheism, adopted good morals giving up evil morals, and performed good deeds giving up evil deeds. Success dces not imply worldly prosperity, but true and real success whether worldly prosperity accompanies it or not. (For explanation, see E.N. 23 of Yunus, E.N.'s 1, I 1-50 of Al-Mu'minun, E.N. 4 of Luqman).
