According to
Islamic texts, Jesus was neither killed nor crucified, but rather He was raised alive up to Heaven. Islamic traditions narrate that He will return to Earth near the Day of Judgement to restore justice and defeat al-Masīḥ ad-Dajjāl (lit. “the false messiah”, also known as the Antichrist).
Hi
The PromisedMessiah 1835-1908 has explained the correct scenario:
The arguments which I am now going to set out, might seem to be useless so far as they are meant for Christians, for these people are not bound by what the Holy Quran or the Hadith say on this question; but I state them because I wish Christians to know of a miracle of our Holy Quran and Holy Prophet; to tell them that the truth which has been discovered after hundreds of years has already been proclaimed by our Holy Prophet and Holy Quran. Accordingly, I set down some of it below.
Almighty God says in the Holy Quran

4:158) The Jews neither murdered Jesus, not did they kill him on the Cross; no, they only suspected that Jesus had died on the Cross; they did not have proof which could have convinced and satisfied them that Jesus (on whom be peace) had really died on the Cross.
In these verses Almighty God states that although it is true that Jesus was apparently placed on the Cross, and that they were determined to kill him; yet, it is wrong for Jews and Christians to suppose that Jesus did really die on the Cross. No, God created circumstances which saved Jesus from death on the Cross.
Now, if one were just, one must say that what the Holy Quran had said against Jews and Christians turned out ultimately to be true. Investigations of a very high standard to-day have proved that Jesus had really been saved from death on the Cross. A study of the records shows that the Jews have never been able to reply to the question: How was it that Jesus died within two or three hours when his bones were not broken?
This has led the Jews to put in another plea – that they killed Jesus by the sword, whereas the ancient history of the Jews does not show that Jesus was killed by the sword. The majesty and power of the Divine Being made it dark in order that Jesus might be saved. There was an earthquake. Pilate’s wife saw a vision. The Sabbath night was about to fall, when it was improper to let a crucified body remain on the Cross.
The magistrate, because of the terrible dream, became disposed towards the release of Jesus. All this was brought about simultaneously by God to save Jesus. Jesus himself was made to go into a swoon that he might be taken for dead. Through terrible signs like the earthquake, etc. there were produced in the Jews cowardice, and fear, and also fear of heavenly punishment. There was also the fear lest the corpses should remain on their crosses during the Sabbath night. Again, the Jews, seeing Jesus in a swoon, thought that he was dead. It was dark. And there was an earthquake and great excitement. They also became anxious about their homes – how must the children be feeling in that darkness and earthquake? There was also a terror in their hearts that if this man was a liar and a Kafir, as they thought he was, why were mighty signs manifested at the moment of his suffering – signs which had not been manifested before.
They were so upset that they no longer were in a position to satisfy themselves whether Jesus had really died, or what exactly his condition was. What had come about, however, was a Divine Design to save Jesus. This is hinted at in the verse… i.e., the Jews did not kill Jesus – God made them believe that they had killed him. This circumstance encourages the righteous to place great trust in God, that God can save His servants as He pleases.

I think it reasonably explains the incident of Crucifixion; made a mystery by Paul and his associates.
