Jesus Will Return

From: http://www.whyislam.org/

Jesus (peace be upon him) will return as a savior of the believers
Jesus (I'sa) (peace by upon him), just as all the other prophets, is a chosen slave of Allah whom Allah assigned to summon people to the true path. However, there are some attributes of Jesus distinguishing him from other prophets, the most important one being that he was raised up to Allah and that he will come back to earth again.
Contrary to what most people believe, Jesus was not crucified and killed nor did he die for any other reason. The Quran tells us that they did not kill him and they did not crucify him and that Allah raised him up to Him. In none of the verses, is there an actual reference to his murder or that he was killed, apart from the verse (ayah) which denies that it happened. Furthermore, the Quran acquaints us with some events from the life of Jesus which have not yet happened. Thus, his second coming to earth is a prerequisite for these events to happen. There is no doubt that the Quran's revelations will surely happen.
Despite this, however, many people assume that Jesus passed away some thousands of years ago and that thus it is unlikely that he will return. This is a misconception arising from lack of knowledge about the Quran and the Sunnah. A careful scrutiny of the Quran will render an accurate understanding of the verses about Jesus possible.
Our Prophet also told us that Jesus will be sent back to earth and related that in that time, which is called "the end of time", there may be a period in which the earth will attain unprecedented peace, justice and welfare. The "end times" refers to the period of time close to the end of the world. According to Islam, in this time, there will be the terrible trials of the Dajjal (Anti-Christ), many earthquakes and the emergence of Yajuj and Majuj (Gog and Magog) after which the ways of the Quran will prevail and people will extensively adhere to the values it introduces.
In their dreams, people always long for better. A more beautiful landscape, a more delicious food, a more socially promising society .. The later period of "the end of time" expresses a period which entirely embraces all these favorable concepts, "the better", "the more beautiful" etc. It is a blessed period people have been longing for ages. It is the glorious time of welfare and abundance, of justice and peace. It is the time when all these blessings will supersede injustice, immorality, conflict and wars. It is surely the blessed time when Islamic morals will penetrate to every aspect of life.
THE EXPECTED SAVIOR In every age, Allah answered the call of His slaves who desperately needed His help. This also holds true for this age and for the future. As it was the case with the earlier ages, in our day, too, it is expected that Allah will save people from the injustice of the system of disbelief and present them with the beauties of Islam.
It is especially expected that the Islamic world will find a way out of the corruption it experiences today and the sincere believers will communicate the values of Islam to the whole world. Surely, as in every age, today people hope that a savior will appear. This savior, who will take mankind from the "darkness to the light," is the religion of Islam. The people leading the way to live by these superior values will defeat all the systems that deny Allah, and they will render corrupted ideologies invalid.
In brief, Allah will help each people as He did in previous ages. Allah promises this to His slaves who sincerely turn to Him and have deep fear of Him.
THE RETURN OF JESUS TO EARTH An examination of the verses about Jesus in the Quran indicates that Jesus neither died nor was killed, but he was raised to the presence of Allah. In Surat an-Nisa, it is related that Jesus was not killed but raised to the presence of Allah. The related verse follows:
And (on account of) their saying, "We killed the Messiah, 'Isa son of Maryam, Messenger of Allah." They did not kill him and they did not crucify him but it was made to seem so to them. Those who argue about him are in doubt about it. They have no real knowledge of it, just conjecture. But they certainly did not kill him. Allah raised him up to Himself. Allah is Almighty, All-Wise. (Surat an-Nisa: 157-158)
From what has been related so far, it is clear that Jesus did not die but was raised to the presence of Allah. However, there is one more point that is underlined by the Quran: Jesus will come back to earth. That Jesus will come back to earth towards the end of time is related in another verse 43:61. [detailed references are available in the book related to other verses: 3:45-48; 3:55; 4:157-159].
Starting from Surat az-Zukhruf: 57, there is reference to Jesus :
"When an example is made of the son of Maryam ('Isa) your people laugh uproariously. They retort, 'Who is better then, our gods or him?' They only say this to you for argument's sake. They are indeed a disputatious people. He is only a slave on whom We bestowed Our blessing and whom We made an example for the tribe of Israel." (Surat az-Zukhruf: 43-59)
If We wished, We could appoint angels in exchange for you to succeed you on the earth. (Surat az-Zukhruf: 43-60) Just after these verses, Allah declares that Jesus is a sign of the Day of Judgment. He is a Sign of the Hour. Have no doubt about it. But follow me. This is a straight path. (Surat az-Zukhruf: 43:61)
Ibn Juzayy says that the first meaning of this verse is that Jesus is a sign or a precondition of the Last Hour. We can say that this verse is a clear indication that Jesus will come back to earth at the end times. That is because Jesus lived six centuries before the revelation of the Quran. Consequently, we cannot interpret his first coming as a sign of the Day of Judgment. What this verse actually indicates is that Jesus will come back to earth towards the end of time, that is to say, during the last period of time before the Day of Judgment and this will be a sign for the Day of Judgment. Allah surely knows the best.
The Arabic of the verse "He is a Sign of the Hour" is "Innahu la 'ilmun li's-sa'atiÉ" Some people interpret the pronoun "hu" (he) in this verse as the Quran. However, the preceding verses explicitly indicate that Jesus is mentioned in the verse: "He is only a slave on whom We bestowed Our blessing and whom We made an example for the tribe of Israel" [1]
In Sahih Muslim, it is also stated that the Hadith in which it is said that the Prophet Jesus will descend amongst people at the end of time have reached the degree of being mutawatir, i.e. narrated by so many people in each generation that it is not possible to have any doubt of their authenticity, and that it is counted as one of the major signs of the Day of Rising. (Sahih Muslim, 2/58)
