﴿ إِذًۭا لَّأَذَقْنَٰكَ ضِعْفَ ٱلْحَيَوٰةِ وَضِعْفَ ٱلْمَمَاتِ ثُمَّ لَا تَجِدُ لَكَ عَلَيْنَا نَصِيرًۭا ﴾

“in which case We would indeed have made thee taste double [chastisement] in life and double [chastisement] after death, and thou wouldst have found none to succour thee against Us!”

Then had you inclined We would have surely made you taste a double chastisement in life and a double chastisement upon death in other words twice the chastisement that any other person would receive in this world and the Hereafter. Then you would not have found for yourself any helper against Us anyone to shield you from it.
