(John 14:16): "And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever."
We do not know exactly the original Aramaic word used by Jesus for "Comforter." Other Bibles use "Consoler," “Advocate," "Helper," and in Greek Bibles we find the word "Paraclete." There are different explanations for it: "Holy Spirit", "the Word”, a person, etc.
The Holy Qur'an states in Surah 61:6 (English meaning) that Jesus explicitly mentioned the name Ahmad: "And (remember) when Jesus, Son of Mary, said: 'O, children of Israel! I am the Apostle of Allah (sent) to you confirming the Torah (which came) before me, and giving glad tidings of an Apostle to come after me, whose name shall be Ahmad (i.e. the second name of Prophet Muhammad, and literally it means "the one who praises Allah more than others")."
Whatever the explanation is of the Comforter, we conclude that Jesus left an unfinished work and that someone was coming to complete his mission. Let us examine, in the light of the Bible, if this Comforter fits the character of Prophet Muhammad (pbuh):
1. "Another Comforter": So, many Comforters had come and another one was to come.
2. "That he may abide with you for ever": As there was no need for another one to come after him, and he was the Seal of all Prophets. The teaching will abide for ever, and will remain intact. In fact, the Holy Qur’an and all his teachings remain as they were 1400 years ago.
3."He will reprove the world of sin" (John 16: 8): All other prophets, even Abraham, Moses, David, and Solomon chastised their neighbors and their people for sin, but not the world as Muhammad (pbuh) did. He not only rooted out idolatry in Arabia within a 23-year period, but also sent envoys to Heraclius, the Sovereigns of the empires of Persia and Rome, to Najashi (the King of Ethiopia), and to Muqauqis (the Governor of Egypt).
He reprimanded the Christians for dividing the Unity of God into trinity, for having raised Jesus to Son of God and God Himself. It was he who condemned the Jews and Christians for having corrputed their Scriptures, demonstrated the birthright of Ishmael (pbuh), and cleared the Prophets from accusations of adultery, incest, rape, and idolatry.
4. "The prince of the world is judged" (John 16:11). This is Satan, as explained in (John 12:31 and 14:30). So Prophet Muhammad (pbuh) came to chastise the world on account of judgment.
5. "The Spirit of Truth" (John 16:13). Since childhood, Prophet Muhammad (pbuh) was called al-Ameen, i.e. the Honest or Truthful One, and "he will guide you into all truth: ..." (John 16:13).
6. "For he shall not speak of himself, but whatsoever he shall hear, that shall he speak" (John 16:13).
The Holy Qur'an is God's word. Not a single word from Prophet Muhammad (pbuh) or his Companions was included. The angel Gabriel read it to him, he memorized it and it was written down by his scribes. His own sayings and teachings were recorded in Hadith or Tradition.
Compare with (Deuteronomy 18:18): "... and will put my words in his mouth; and he shall speak unto them all that I shall command him." This corresponds with Surah 53:2-4 (English meaning): "Your companion [Muhammad] is neither astray nor being misled. Nor does he speak of [his own] desire. It is only the inspiration that is inspired."
7. "And he will show you things to come" (John 16:13). All prophecies of Prophet Muhammad (pbuh) came to pass.
8. "He shall glorify me” (John 16:14). Actually, the Holy Qur’an and Prophet Muhammad (pbuh) have more reverence for Jesus than the Bible and Christians themselves. The following will clarify:
a) To believe in his death on the cross discredits his prophethood, according to (Deuteronomy 13:5): "And that prophet, or that dreamer of dreams, shall be put to death ..." It also stamps him as accursed, (May Allah forbid!) according to (Deuteronomy 21:22-23): "... for he that is hanged is accursed of God . .."
b) (Matthew 27:46): "... My God, my God, why hast thou forsaken me?" Could this not come from someone other than Jesus? Even a non-prophet would smile at agony as he knew that his death would win him the title of martyr. Was this not an insult to Jesus in not having faith in Allah?
c) We Muslims cannot believe that Jesus could label the Gentiles as dogs and swine and address his mother with "Woman," as the Holy Qur’an states in Surah 19:32 (English meaning): "And dutiful to my Mother [i.e. Mary], and [Allah] made me not an unblessed and arrogant". Compare (Matthew 7:6): "Give not that which is holy unto the dogs, neither cast ye your pearls before swine ..."; (John 2:4): "Jesus saith unto her [Mary], Woman, what have I to do with thee?"
15. Revelation to Prophet Muhammad
The first revelation of Allah through the angel Gabriel to Muhammad (pbuh) was the word “Iqra’,” which means "Read”, in Surah 96:1-5. As he was illiterate, he replied: "I cannot read." This first revelation was prophesied in (Isaiah 29:12): "And the book is delivered to him that is not learned, saying: 'Read this, I pray thee,' and he saith: 'I am not learned’.”
The order of the revelations is not as the order it is seen in the Qur’an. In other words, the first part revealed is not in the first page and the last part revealed is not in the last page. That these revelations came in instalments and inserted in certain order in the Qur’an as ordained by Allah, was also mentioned in (Isaiah 28:10-11): "For precept must be upon precept, precept upon precept; line upon line, line upon line; here a little, and there a little: For with stammering lips and another tongue will he speak to his people”. Another tongue means here another language, not Hebrew or Aramaic, but Arabic
Muslims all over the world are using one language "Arabic" in calling their God, in their prayers, pilgrimage, and in their greetings to each other. Also this unity of language had been prophesied in (Zephaniah 3:9): "For then will I turn to the people a pure language, that they may all call upon the name of the Lord, to serve him with one consent." Alas the Truth has come in Arabic, but some still expect Prophet Jesus (pbuh), who might teach mankind to worship Allah in one unique language in his second coming. We Muslims are sure that Prophet Jesus, in his second coming, will join the Muslims in their mosques, as he is like any other Muslim, circumcised, not eating pork, and performing prayers with ablution, standing, bowing, and prostration.
