Zalim and Babar
Let's just get a few things quite clear here.
At no time does the Qur'aan mention what happened to Jesus after he was saved from the crucifixion. This is agreed upon by all.
Therefore, the ayat you are trying in vain to confirm Jesus's migration is not applicable or correct in your interperotation.
The context of this ayat is relating to Mary and Jesus at the time when Mary was chosen and after the Birth of Jesus:
019.016 Relate in the Book (the story of) Mary, when she withdrew from her family to a place in the East.
019.017 She placed a screen (to screen herself) from them; then We sent her our angel, and he appeared before her as a man in all respects.
019.018 She said: "I seek refuge from thee to (Allah) Most Gracious: (come not near) if thou dost fear Allah."
019.019 He said: "Nay, I am only a messenger from thy Lord, (to announce) to thee the gift of a holy son.
019.022 So she conceived him, and she retired with him to a remote place.
019.023 And the pains of childbirth drove her to the trunk of a palm-tree: She cried (in her anguish): "Ah! would that I had died before this! would that I had been a thing forgotten and out of sight!"
019.024 But (a voice) cried to her from beneath the (palm-tree): "Grieve not! for thy Lord hath provided a rivulet beneath thee;
019.025 "And shake towards thyself the trunk of the palm-tree: It will let fall fresh ripe dates upon thee.
019.026 "So eat and drink and cool (thine) eye. And if thou dost see any man, say, ‘I have vowed a fast to (Allah) Most Gracious, and this day will I enter into not talk with any human being’"
One of the reasons why the Qur'aan is a beautiful miracle, is the way the same facts are stated at different periods, in different surahs, with different sentences, but they all mean the same! This has been proven time and time again.
003.054 And (the unbelievers) plotted and planned, and Allah too planned, and the best of planners is Allah.
003.055 Behold! Allah said: "O Jesus! I will take thee and raise thee to Myself and clear thee (of the falsehoods) of those who blaspheme; I will make those who follow thee superior to those who reject faith, to the Day of Resurrection: Then shall ye all return unto me, and I will judge between you of the matters wherein ye dispute.
If Jesus was actually buried in Kashmir, the Vatican would be the first Organisation to move, claim and control the Monopoly.
You may be able to fool and misguide the Tribes people of Africa, but not the majority of Muslims.
