As-Salam aleikum wa rahmatullahi wa baraketuh,
I am really amazed when I read that Christians are still trying to prove that Isaiah 42 foretells Jesus advent (pbuh) - and not Mohammed (pbuh) - by using these miserable arguments based only on translations, and by alluding mostly to the New Testament's content which is not regarded as a historical source according to the Christian scholars themselves. On the other hand, there are a lot of info which clearly indicates that this servant of God must have been originally named as "Ahmed". Also, for instance, the person which was mentioned in Haggai 2:7 as the "desire of all nations" (heb. hemdat) is described as a "Chosen one" similarly to the servant of God from Isaiah 42:1 ! I have a proof from one of the greatest rabbi that the Hebrew term hemed which appears among others in Haggai 2:7 is a proper name! Even Isaiah 53 - a Chapter which perhaps none of muslim would imagine as a prophecy about Muhammed (pbuh) - paradoxically describes Prophet Mohammed (pbuh). How ? Uff...long research brothers, but I will share with you insha'Allah my project, just be patient.
Take care, and salam
Ahmed (Poland, Warsaw)
