:welcome: aboard..
your 'free thinking questions' look awfully familiar.. nonetheless,
You limit God and reduce him when you say, God is to have a son, you should read from the same sura:
6:103 Vision comprehendeth Him not, but He comprehendeth (all) vision. He is the Subtile, the Aware.
also if you have read suret al'ikhlas:
[Pickthal 112:1] Say: He is Allah, the One!
[Pickthal 112:2] Allah, the eternally Besought of all!
[Pickthal 112:3] He begetteth not nor was begotten.
[Pickthal 112:4] And there is none comparable unto Him.
It isn't a matter of 'can't' it is a matter of what would his 'need' be, and the fact that you attribute any need at all to god, would contradict the very definition of divinity.
as for the rest I didn't want to labor over it so here is a cut and paste:
Contradicts these verses:
When Jesus found Unbelief on their part He said: "Who will be My helpers to (the work of) Allah?" Said the disciples: "We are Allah's helpers:
We believe in Allah, and do thou bear witness that we are Muslims. S. 3:52
Ibrahim was not a Jew nor a Christian but he was (an) upright (man),
a Muslim (
musliman), and he was not one of the polytheists. S. 3:67 Shakir
So their argument is pretty much that some Quranic verses say Muhammad is the first Muslim while there are other passages showing that there are Muslims before Muhammad. Is this a contradiction? No, you must understand what Muhammad meant and in what context.
Now when The Quran says:
Say: Shall I choose for a protecting friend other than Allah, the Originator of the heavens and the earth, Who feedeth and is never fed?
Say: I am ordered to be the first to surrender [aslama] (unto Him). And be not thou (O Muhammad) of the idolaters. S. 6:14 Pickthall
Say, verily my Lord hath directed me into a right way, a true religion, the sect of Abraham the orthodox; and he was no idolater. Say, verily my prayers, and my worship, and my life, and my death are dedicated unto God, the Lord of all creatures: He hath no companion.
This have I been commanded: I am the first Moslem (Wa 'Ana 'Awwalu Al-Muslimin). S. 6:161-163 Sale
He hath no associate. This am I commanded,
and I am the first of the Muslims. S. 6:163 Rodwell
Say (O Muhammad): Lo! I am commanded to worship Allah, making religion pure for Him (only).
And I am commanded to be the first of those who are muslims (surrender unto Him). S. 39:11-12 Pickthall
What this basically and simply means that Muhammad is commanded to be the first Muslim AMONG HIS PEOPLE. That is all it means, it means that Muhammad is the first Muslim among his people, and is commanded to be the first Muslim among his people. So it does not contradict the other verses, Muhammad is not the first Muslim on the planet, it just means the first Muslim among his people. Note what one of the verses also say:
Say: Shall I choose for a protecting friend other than Allah, the Originator of the heavens and the earth, Who feedeth and is never fed?
Say: I am ordered to be the first to surrender [aslama] (unto Him). And be not thou (O Muhammad) of the idolaters. S. 6:14 Pickthall
It tells Muhammad to be not of the idolaters, who were the idolaters? The idolaters were the Quraysh, they were Muhammad's people, so hence it is crystal clear when it is said for Muhammad to be the first Muslim it just basically means among his people.
So hence the passages of Muhammad being commanded to be the first Muslim do not contradict these passages:
When Jesus found Unbelief on their part He said: "Who will be My helpers to (the work of) Allah?" Said the disciples: "We are Allah's helpers:
We believe in Allah, and do thou bear witness that we are Muslims. S. 3:52
Ibrahim was not a Jew nor a Christian but he was (an) upright (man),
a Muslim (
musliman), and he was not one of the polytheists. S. 3:67 Shakir
They are not all alike; of the followers of the Book
there is an upright party; they recite Allah's communications in the nighttime and they adore (Him). They believe in Allah and the last day, and they enjoin what is right and forbid the wrong and they strive with one another in hastening to good deeds, and those are among the good. And whatever good they do, they shall not be denied it, and Allah knows those who guard (against evil). S. 3:113-115 Shakir
Then will Allah say: "O Jesus the son of Mary! Recount My favour to thee and to thy mother. Behold! I strengthened thee with the holy spirit, so that thou didst speak to the people in childhood and in maturity. Behold! I taught thee the Book and Wisdom, the Law and the Gospel and behold! thou makest out of clay, as it were, the figure of a bird, by My leave, and thou breathest into it and it becometh a bird by My leave, and thou healest those born blind, and the lepers, by My leave. And behold! thou bringest forth the dead by My leave. And behold! I did restrain the Children of Israel from (violence to) thee when thou didst show them the clear Signs, and the unbelievers among them said: ‘This is nothing but evident magic.’ And behold! I inspired the disciples to have faith in Me and Mine Messenger: they said,
'We have faith, and do thou bear witness that we bow to Allah as Muslims.’" S. 5:110-111
Lo! it is from Solomon, and lo! it is: In the name of Allah, the Beneficent, the Merciful; Exalt not yourselves against me, but come unto me as those who surrender (
muslimeena). ... So, when she came, it was said (unto her): Is thy throne like this? She said: (It is) as though it were the very one. And (Solomon said): We were given the knowledge before her and
we had surrendered (wakunna muslimeena) (to Allah). ... It was said unto her: Enter the hall. And when she saw it she deemed it a pool and bared her legs. (Solomon) said: Lo! it is a hall, made smooth, of glass. She said: My Lord! Lo! I have wronged myself, and
I surrender (aslamtu) with Solomon unto Allah, the Lord of the Worlds. S. 27:30-31, 42, 44 Pickthall
And strive in His cause as ye ought to strive, (with sincerity and under discipline). He has chosen you, and has imposed no difficulties on you in religion; it is the cult of your father Abraham.
It is He Who has named you Muslims, both before and in this (Revelation); that the Messenger may be a witness for you, and ye be witnesses for mankind! So establish regular Prayer, give regular Charity, and hold fast to Allah! He is your Protector - the Best to protect and the Best to help! S. 22:78
So there is no contradiction what so ever. Adam was indeed the first Muslim, the first Muslim among mankind. Muhammad is commanded to be the first Muslim among his people. That is all that is meant by Muhammad being the first Muslim.
Since we are on the topic of the word Muslim and who is a Muslim etc. Here is a link in which you can see that Jesus himself used the word Muslim in the Bible:
all the best
