Assalaamu alaikum dear brothers,
Since 2 years I have focused more on Islam's engagement with Hinduism. But there was an article of mine that I hstarted but not finished. Alhamdulillah, got to finish it today. Isaiah 42 describes Prophet Muhammad al-Mustafaa Here is the link
http://www.mushafiqsultan.com/isaiah-42-describes-prophet-muhammad-al-mustafaa/Although you have dedicated few articles on your website to this topic, still I have attempted to look at this chapter from another perspective and hope that people will find it beneficial. I have seen a lot of Chrisitian debaters ask this question that where did the contemporaries of Prophet Muhamamd (sws) find him in the Torah and the Gospel? I have tried to deal with this. I request brother Osama Abdullah to take some of his precious time and kindly read it. If you find it good, then you can share it on your website. Waiting for your feedback.
Regards
