The definition of "Son of God" in Islam

The current Bible's "Son of God" expression is not accurate and is far away from the Truth as far as Islam is concerned. Allah Almighty never beget any son. He corrected the Jews' and Christians' "Son of God" misunderstanding in the Noble Quran:
"And they say: "(God) Most Gracious has begotten offspring." Glory to Him! they are (but) servants raised to honour. (The Noble Quran, 21:26)"
The people whom the Jews and Christians call "sons of God" in the Bible, are only servants of Allah Almighty that were raised with honour. These people are Allah Almighty's Messengers and Prophets. GOD Almighty doesn't need a son nor a wife to help Him in anything. He is the Absolute, One, Living True King, and GOD Almighty:
"Say: He is God, the One and Only; God, the Eternal, Absolute; He begetteth not, nor is He begotten; And there is none like unto Him. (The Noble Quran, 112:1-4)"
The Bible too claims this about GOD Almighty [1] [2], but yet Christians still insist on insulting GOD Almighty (sorry to say that) and divide Him into three gods! Jesus peace be upon him himself refuted the trinity deception and never really praised it in the Bible. He even worshiped GOD Almighty Himself!
