no Jesus is not the messiah neither the son of God
Jesus is a simple human and a servant of God
Muhammad had the same Greek scriptures (Bible) we have today. The scriptures have not been altered since Muhammad's time. Pictures of those Greek manuscripts are available online... and they look now, as they did in Muhammad's time. Muhammad said that we should search these Greek scriptures (that we have pictures of online) and see the truth revealed therein...
Bahous, when God, in these Greek scriptures,
announced from heaven that Jesus is His Son, what do you suppose God meant by it?
You cannot deny that this was declared in the scriptures Muhammad had access to... if, as you say, Jesus is not God's son, then why would Muhammad affirm that passage that DOES say that Jesus is God's son?
