what these three prophet not mentionned in Quran , and we considerate them Prophets ?You will be surprised to know that although these three prophets are not mentioned in the Qur'an, they are certainly considered as prophets in Islamic tradition.
Furthermore, if you still disregard them. Then we have plenty of other examples. There are no Islamic alternatives for the Biblical narratives about King David and Solomon, and those prophets of the People of Israel who ARE mentioned in the Qur'an. And of course no Islamic alternatives for the narratives about Jesus in the gospels.
then if the Quran was wrote by Muhammad (pbuh) , how you explain that the people of Israel and other Prophets mentionned more than his name ?
that's just a doubt , had no historic evidence , because Muhammad (pbuh) was Illiterater , and it's highly impossible for illiterate to wrote something or tell something like the Quran .But I just said that the word 'copy' is irrelevant. Muhammad and his followers did not 'copy' Judaism, they discussed Abrahamic traditions. I am saying that the Arabs knew the Jewish Abrahamic traditions before they became Muslims, and Muhammad and the Qur'an discussed these traditions more directly in the context of Monotheism, or what has emerged as Islam. It was a regional development.
for that we all the muslims believe :
Quran is sent by God to Prophet Muhammad (pbuh) by angel Gabrial .
