COMMENTARY on 39:48
A. Yusuf Ali:

Translation:
For the evils of their Deeds will confront them, and they will be (completely) 4317 encircled by that which they used to mock at!
Commentary:

4317  How humiliating it will be for them to realise that the things they used to mock at are realities all around them, and the things they were so eager to pursue are mere falsehoods or vanities!

 

Muhammad Asad:

Translation:
and obvious to them will have become the evil that they had wrought [in life]: and thus shall they be overwhelmed by the very truth which they were wont to deride. 54
Commentary:
54  Lit., "that which they were wont to deride will enfold them" or "will have enfolded them": i.e., the reality of life after death and of the spiritual truths preached by God’s prophets will overwhelm them.
