Although Jesus is called the Messiah 11 times in 9 surahs, the Koran does not explain the meaning of this word. Hundreds of years before the Koran was written, the significance of the title Messiah, was made clear in the biblical scriptures which the Koran confirms were given by God.
And surely we gave Moses the book (Torah)…(Surah No. 2 Al-Baqarah:87)
Say, We believe in God and … what was given to the prophets from our Lord. (Surah No. 2 Al-Baqarah:136)
… and we gave David the Psalms (Zabur)(Surah No. 4 An-Nisa:136)
And we sent, following in their footsteps, Jesus son of Mary, confirming the Torah before him; and we gave to him the Gospel (Injil) which contains guidance and light, and confirming the Torah before it, as a guidance and an admonition for the pious(Surah No. 5 Al Ma'ldah:46)
Moreover, the Koran exhorts the faithful to believe in the biblical Scriptures given before the time of Muhammad:
O believers, believe in God … and the scriptures which He revealed before. Whoso disbelieves in god and His angels and His Scriptures and His messengers and the Last Day, he surely has gone astray into far error.(Surah No. 4 An-Nisa:136)
As you read the quotations from the Bible and the Koran you will be able to judge whether Jesus son of Mary is the Messiah promised by the prophets, and what that means to all mankind.
In the name of the living and eternal God you are invited to read all seven booklets to understand who the Messiah 'Isa is.
