Muhammad got four historical facts wrong and therefore could not be a prophet:
1) He claims Miriam, the sister of Moshe was the mother of Yeshki (Jesus), Quran – Suras 19:27-28, 3:35-36, 66:12;
2) he claims Haman of Megillat Esther was in the “court” of Pharaoh; confusing the Building of the Tower of Babel with Haman and Pharaoh, Quran – Sura 40:36-37;
3) and he claims that Pharaoh used the Roman method of crucifixion as a form of the death penalty, Qur’an – Suras 7:124, 12:41, 20:71, 26:49; 38.12, 89:6-12;
4) and conflicting Islamic sources claim either Isaac or Ishmael was offered on the Altar by Avraham.
