Since we are at the topic of the Gospel, allow me to refute your silly arguments:
1. Notice that the hadith mentioned the word 'Gospel', not "Gospels (plural)".
2. There might be other "Gospels" circulating around the Hijaz at that time. What makes you think Waraqa was referring to the Gospel according to Mark, Matthew, Luke and John?
3. You insinuated that Waraqa bin Naufal, Jabal, "Umm Habbibah, was formerly the wife of a Christian, Ubaidu'llah ibn Jahsh. Another wife of Mohammed, Miriam, and her sister, Sirin, were Christian slaves given to Muhammad".... Question is: WHICH ONE ACTUALLY?
Scholars who studied the Quran would tell you that the language, style, of the Quran is consistent throughout the whole 30 Juz. There is only ONE author of the Quran. We believe it is God. If you believe otherwise, tell me the author and provide me the evidence.
