Wallatheena hum min AAathabi rabbihim mushfiqoon (surah Maarij: 27)

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

(70:27) and fear the chastisement of their Lord *18'

Wallazeena hum min `azaabi Rabbihim mushfiqoon

*18) In other words, they are not like the disbelievers, who do not fear God even after they have committed every heinous sin and crime and perpetrated every cruelty in the world, but they, in spite of having adopted a righteous attitude in morals and deeds as best as they could, fear God and continue to remain in constant awe lest their shortcomings should exceed their good works before Him and they should be declared as worthy of punishment. (For further explanation, see E N. 54 of Al-Mu'minun, E.N. 19 of Adh-Dhariyat).
