Almuntakhab Fi Tafsir Alquran Alkarim

But then, by consequence, We would have made you taste a double punishment in life and at death, besides the second death, and no protector would be found to render void Our decree

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

(17:75) But if you had done so, We would have made you taste double chastisement in this world as well as in the Hereafter: then you would have found no helper against Us. *88

Then [if you had], We would have made you taste double [punishment meaning

*88) This review implies two things: (1) "If you had compromised with falsehood after recognizing the Truth, you might have pleased your degenerate people but would have incurred the wrath of Allah and would have received double chastisement both in this world and in the Hereafter." (2) "No man, not even a Messenger of Allah, can fight single-handed against the deceitful methods of falsehood, unless he receives the succour of Allah." It was the fortitude which Allah had bestowed upon the Holy Prophet, which helped him to retrain steadfast on the right position he had taken, so that no persecution, howsoever great, could turn him away in the least from that position.
