Logic says that if 4 different people are talking about the same incident, there must be some variations in details…
I agree. In that case, logically we will not take any single report to reconstruct the exact event. Will we? If 4 report differ in detail, we can conclude that the actual event could be something similar but not exactly as in any report.
And then logically, if 4 reports of the same event differs with one another, we know that these are humanly error as writers reporting it according to the information they got and their understand of the event. But if you claim a spiritual inspiration in those writings, the issue is different.
but what would we conclude about the Quran, written allegedly by 1 all-knowing author, yet presenting us with the same incidents in differing details, like in:
“Behold! We sent To thy mother, by inspiration, The Message: Throw (the child) Into the chest, and throw (The chest) into the river: The river will cast him Up the bank, and he will be taken up by one Who is an enemy to Me And an enemy to him': But I cast (the garment Of) love over thee from Me: And (this) in order that Thou mayest be reared Under Mine eye. Behold thy sister goeth forth And saith, Shall I show you One who will nurse And rear the (child)?’ So We brought thee back To thy mother, that her eye Might be cooled and she Should not grieve. Then thou didst slay A man, but We saved thee From trouble, and We tried Thee in various ways. Then didst thou tarry a number of years With the people of Midian. Then didst thou come hither As ordained, O Moses!” [S. 20:38-40]
"So we sent this inspiration To the mother of Moses: `Suckle (thy child), but when Thou hast Fears about him, Cast him into the river, But Fear not nor grieve: For We shall restore him To Thee, and We shall make Him one of Our apostles… And she said to the sister Of (Moses), “Follow him”. So she (the sister) Watched him In the character of a stranger. And they knew not. And We ordained that he Refused suck at first, until (His sister came up and) said: "Shall I Point out to you the people Of a house that will nourish And bring him up For you And be sincerely attached To him?.. Thus did We restore him To his mother, that Her eye might be comforted, that she might not grieve, and that She might know the promise of God is true: but Most of them do not understand. [S. 28:7,11-13]
or maybe the 3 different passages talking about Moses and the burning bush yet the author is supposed to be one and all-knowing?
Use logic again. God quoting history to clear certain points. As far as he is not reporting the actual event with complete details, we do assume the same thing that, the actual event happened in the life of Moses (a) could be something similar as mentioned in different passages. As the Monotheistic faith and message of Moses (a) is clear in the Quran we are not worried about reconstructing the entire life of Moses (a). Even if a recunstructon, it is possible with the above passages without any difference or contradiction. Look below.
Here God speaking to Mother of Moses (a).
"So we sent this inspiration To the mother of Moses: `Suckle (thy child), but when Thou hast Fears about him, Cast him into the river, But Fear not nor grieve: For We shall restore him To Thee, and We shall make Him one of Our apostles…
Here God mentioning that event to Moses (a).
“Behold! We sent To thy mother, by inspiration, The Message: `Throw (the child) Into the chest, and throw (The chest) into the river: The river will cast him Up the bank, and he will be taken up by one Who is an enemy to Me And an enemy to him’: But I cast (the garment Of) love over thee from Me: And (this) in order that Thou mayest be reared Under Mine eye.”
Here Mother of Moses (a) asking his sister to follow him.
“And she said to the sister Of (Moses), “Follow him”. So she (the sister) Watched him In the character of a stranger. And they knew not.”
Here God mentioning that and the question she asked.
“Behold thy sister goeth forth And saith, `Shall I show you One who will nurse And rear the (child)?’”
Here God gives the reason for the requirment of a lady to breed him with the question of sister in detail without any contradiction in the meaning.
"And We ordained that he Refused suck at first, until (His sister came up and) said: “Shall I Point out to you the people Of a house that will nourish And bring him up For you And be sincerely attached To him?..”
Here God gives the reason for all these scenes.
“So We brought thee back To thy mother, that her eye Might be cooled and she Should not grieve.”
Here God gives the reason with more detail.
“Thus did We restore him To his mother, that Her eye might be comforted, that she might not grieve, and that She might know the promise of God is true:”
Here God gives his point of mentioning the event in S. 28:7,11-13. God talking about people who disbelieve even after seeing God fulfilling his promises
“but Most of them do not understand”.
Here God gives his point of mentioning the event in S. 20:38-40. God explaining Moses (a) what all he did for him.
Then thou didst slay A man, but We saved thee From trouble, and We tried Thee in various ways. Then didst thou tarry a number of years With the people of Midian. Then didst thou come hither As ordained, O Moses!"
Come on inJESUS, lets do it in the spirit of learning each other. I always thought you are better than anyone in the forum and knows many things about Islam. But disappointing.
