Assalamualaikum,Is there anyone who read John of Damascus's writing in greek? Well, I know I may be thinking too much but I read an article where it say something very uncomfortable things like:"Muhammad" lived in mecca as islami tradition say but he is author of early mecca sura on the other hand "Mamed "mentioned by John of Damascus and others is another one who authored medinan sura.I don't understand how he came to that conclusion cause I stopped reading as it's clearly anti islamic but it's bothering me.I have read than in a greek arabic papyri Muhammad mentioned as "MAAMET" in greek,so is there any significant change if later people call him as Mamed?
