We are very surprised by what you mentioned about Muslims’ disrespect for Jesus, peace be upon him. Jesus, peace be upon him, is mentioned in the Holy Qur’an sixteen times, every time with respect and honour. You can refer to the Holy Qur’an and find that out with more depth. Here we mention one of those verses, in which God Almighty said: "And verily We gave unto Moses the Scripture and We caused a train of messengers to follow after him, and We gave unto Jesus, son of Mary, clear proofs..." (Qur’an, 2:87). The Holy Qur’an speaks of the prophets with great respect and reverence, as it considers them to be purified from any imperfection. The Holy Qur’an pays more respect and gives greater sanctity to the prophets than the Bible does. You can study both books in an objective manner to see this truth clearly. You can also notice that Muslims do not mention the name of Jesus without saying “peace be upon him”, which is a phrase they do not say but for those who are loyal to God.
