COMMENTARY on 17:88
A. Yusuf Ali:

Translation:
Say: "If the whole of mankind and Jinns 2288 were to gather together to produce the like of this Qur´an, they could not produce the like thereof, even if they backed up each other with help and support. 2289
Commentary:

2288  For the meaning of "Jinns", see n. 929 to 6:100.

2289  The proof of the Qur'an is in its own beauty and nature, and the circumstances in which it was promulgated. The world is challenged to produce a Book like it and has not produced one. It is the only revealed Book whose text stands pure and uncorrupted today. Cf., for a similar challenge, 2:23,10:38, and 11:13.

 

Muhammad Asad:

Translation:
Say: "If all mankind and all invisible beings 103 would come together with a view to producing the like of this Qur'an, they could not produce its like even though they were to exert all their strength in aiding one another!"
Commentary:
103  See Appendix III.
