Surah Al Jumu'ah Tafseer

Say:

"Verily, the death from which you flee will surely meet you, then you will be sent back to the Knower of the unseen and the seen, and He will inform you about what you used to do."

is like His saying in Surah An-Nisa':

أَيْنَمَا تَكُونُواْ يُدْرِككُّمُ الْمَوْتُ وَلَوْ كُنتُمْ فِى بُرُوجٍ مُّشَيَّدَةٍ

Wheresoever you may be, death will overtake you even if you are in fortresses built up strong and high
