Jesus Christ of the New Testament is not the same as Isa in the Quran. Isa is a retconned version of Jesus, and denies pretty much his entire message, and instead is much like the new Star Wars movies, getting an old character to 'endorse' Mohammed, like Han and Luke with Rey. Plus the Quran totally botches the lineage by calling Maryam's dad 'Imran', which is Arabic for Amram, who is the father of Miriam in the OLD Testament, who is sister to Aaron, which muslims will also say about Isa's mom Maryam. The Old Testament created The Law, but man began to make hyocritical laws in God's name - so Jesus SUMMARIZED - consolidated - The Law to simply the Golden Rule. Therefore Jesus CERTAINLY would not advocate Islam, whose Allah will curse someone who would simply pluck an eyebrow.
