Surah Al Isra Tafseer

Say:"If mankind and the Jinn were together to produce the like of this Qur'an, they could not produce the like thereof, even if they helped one another."

And indeed We have fully explained to mankind, in this Qur'an, every kind of similitude, but most of mankind refuse (the truth and accept nothing) but disbelief.

Then Allah points out the great virtue of the Qur'an, and says that even if mankind and the Jinn were all to come together and agree to produce something like that which was revealed to His Messenger, they would never be able to do it, even if they were to cooperate and support and help one another. This is something which is impossible. How could the words of created beings be like the Words of the Creator Who has no equal and peer, for there is none like unto Him

وَلَقَدْ صَرَّفْنَا لِلنَّاسِ

And indeed We have fully explained to mankind,

meaning, `We have furnished them with evidence and definitive proof, and We have shown them the truth and explained it in detail, yet despite that most of mankind insist on disbelief, i.e., denying and rejecting the truth.
