Translation:

10. `And we understand not whether ill is intended to those on earth or whether their Lord (really) intends to guide them to right conduct.

Notes (Tafseer)

5735. To these jinns this gospel is yet new, and appears like a flaming sword which destroys falsehood while it protects Truth. They frankly confess that they do not clearly understand whether on the whole it will be a mercy to mankind or a punishment for mankind forsaking the paths of Allah. But they rightly feel that it must be a blessing if all seek right Guidance.
