what jesus christ (A.S.) told of the coming of Prophet Muhammad (S.A.W)

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 Qur'an) 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 Qur'an says,
And surely they slew him not. But Allah (God) raised him unto Himself.
(Holy Qur'an, 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. His body was so clean and clear, that it appeared as though he had just performed ghusal (ablution, cleansing of the entire body) and come." In 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)."
May Allah Guide all people to the Truth. Aameen.
