Muslims do believe that Isa (A.S.) was sent down as a Prophet of Allah (God), but he (Jesus) is not God or Lord, nor the son of God.
Muslims do not believe that Isa (A.S.), also known as Jesus by Christians and others, is dead or was ever crucified. We believe that he was raised to heaven and is there, and will descend at the appointed time, end all wars, and bring peace to the world. Like Jesus (A.S.), Muhammad (Peace be upon him) is also a Prophet and Messenger. Muhammed (P.B.U.H.) is the last Prophet, though, and there is none after him. Hence, Islam is the last religion, complete, with the Holy Quran as the unchanged and perfect word of God for over 1400 years, as God promised to preserve it till the last day for all of humankind, unlike sacred texts of other religions which have multiples versions and are “revised” periodically. God, or Allah in Arabic, is Divine and Supreme Being and Creator.
What the Holy Quran says about Jesus:
They slew him not, nor did they crucify him but it was made dubious to them.
(Holy Quran, Surah Nisaa, Verse 157)
Hadhrat Isa (A.S.) himself told of the coming of Prophet Muhammad (Peace be upon him). In the Bible, Jesus (A.S.) says,
If you love me, keep my commandments. And I will pray to the Father and He shall give you another comforter that he may abide with you forever.
(Bible, John 14-15/16)
But when the comforter is come, whom I will send unto you from the Father, even the spirit of Truth, which proceedeth from the Father, he shall testify of me, and he also shall bear witness, because ye have been with me from the beginning.
(Bible, John 15-26/27)
I have yet many things to say unto you, but you cannot bear them now. How be it when he, the spirit of Truth will come, he will guide you into all truth, for he shall speak not of himself, but whatsoever he shall hear, that he shall speak, and he will show you things to come. He shall glorify me, for he shall receive of mine, and he shall show it unto you.
(Bible, John 16-12/14)
Ulema (learned scholars in Islam) have said that the person who is described by Hadhrat Isa (A.S.) to come after him – in the above verse – does not comply with any other person but Prophet Muhammad (Peace be upon him).
In this case, the “comforter” he mentions is none other than Prophet Muhammad (Peace be upon him) and his laws and way of life (Shariah) and Book (Holy Quran) are those that Hadhrat Isa (A.S.) asks his followers to abide by.
The “person” whom Jesus (A.S.) prophecised will come after him, is called Pargaleeta in the Bible . This word was deleted by interpreters and translators and changed at times to “Spirit of Truth” and at other times, to “comforter” and sometimes “Holy Spirit.” The original Greek and its meaning is “one whom people praise exceedingly.” The sense of the word, then, is applicable to the word Muhammad in Arabic, since Muhammad means “the praised one.”
Jesus (A.S.) also says in the Bible,
…and a little while and you shall not see me; and again a little while, you shall see me because I go to the Father.
(Bible, John 16:16)
… And the Holy Quran says,
And surely they slew him not. But Allah (God) raised him unto Himself.
(Holy Quran, Surah Nisaa, Verse 157-158)
As such, Muslims believe that Hadhrat Isa (A.S.) was raised to heaven. According to Hadith, he is on the second heaven. Rasulullah (Sallallaahu Alayhi Wasallam=Peace be upon him) mentioned, “During the Meraj (Ascension), I met Hadhrat Isa (A.S.) on the second heaven. I found him of medium stature, reddish white. performed ghusal (ablution, cleansing of the entire body) and come.” InHis body was so clean and clear, that it appeared as though he had just another Hadith, Rasulullah (Sallallahu Alayhi Wasallam) mentioned to the Jews that, “Hadhrat Isa (A.S.) is not dead, he will most surely return to you before Qiyamat (the Day of Judgement).”
