Selam brother Ijaz,
I'm very excited you asked this question, and I can't wait for brother Joseph's response
It's a subject I'm studing lately in my personal studies of the Quran. I still need to study more on this topic, but here is portion of the Quran I think might help:
"And We gave to Abraham, Isaac and Jacob - all [of them] We guided. And
Noah, We guided before; and among his descendants, David and Solomon and Job and Joseph and Moses and Aaron. Thus do We reward the doers of good. And Zechariah and John and Jesus and Elias - and all were of the righteous. And Ishmael and Elisha and Jonah and
Lot - and all [of them] We preferred over the worlds." (Al-'An'am, 84-86).
There is also another verse (I can't recall the surah and verse), where Allah says that there were many prophets sent before Muhammad, some of them will be mentioned in the Quran, some of them won't. My guess is that the ones that aren't mentioned in the Quran are only found in Bible. From what I've read, the Quran deals only with those prophets whose life-story or message was corrupted from people. As the rest of them, their stories and messages are in the Bible. Here's an example:
"Have you not considered the assembly of the Children of Israel after [the time of] Moses when they said to a prophet of theirs, "Send to us a king, and we will fight in the way of Allah "? He said, "Would you perhaps refrain from fighting if fighting was prescribed for you?" They said, "And why should we not fight in the cause of Allah when we have been driven out from our homes and from our children?" But when fighting was prescribed for them, they turned away, except for a few of them. And Allah is Knowing of the wrongdoers.
And their prophet said to them, "Indeed, Allah has sent to you Saul as a king." They said, "How can he have kingship over us while we are more worthy of kingship than him and he has not been given any measure of wealth?" He said, "Indeed, Allah has chosen him over you and has increased him abundantly in knowledge and stature. And Allah gives His sovereignty to whom He wills. And Allah is all-Encompassing [in favor] and Knowing." (Al Baqarah, 246-247). The unnamed prophet here is Samuel, whose story is found in the Old Testament part of Bible. Allah wants us not to make distinction between messengers, and the fact that some of them are not named in the Quran doesn't make them inferior to those that were.
Anyways, can't wait for brother Joseph's reply.
God bless you all, selam
