what does Koran 112:3 mean?

Answering Christanity

‎//Giuseppe Maria D'Anunzio
A simple question for my moslem friends with maybe follow up questions to come. My first question: what does Koran 112:3 mean?//

Quran 112

1. Say: "He is Allah, One.'' 2. "Allah As-Samad.'' 3. "He begets not, nor was He begotten.'' 4. "And there is none comparable to Him.''

The reason for the revelation of this Surah has already been mentioned, Ikrimah said, "When the Jews said, `We worship `Uzayr, the son of Allah,' and the Christians said, `We worship the Messiah (`Isa), the son of Allah,' and the Zoroastrians said, `We worship the sun and the moon,' and the idolators said, `We worship idols,' Allah revealed to His Messenger .

Say: "He is Allah, One.'' meaning, He is the One, the Singular, Who has no peer, no assistant, no rival, no equal He is not composed and none comparable to Him. This word (Al-Ahad) cannot be used for anyone in affirmation except Allah the Mighty and Majestic, because He is perfect in all of His attributes and actions. Concerning His saying.

17:111And say, "Praise to Allah, who has not taken a son and has had no partner in [His] dominion and has no [need of a] protector out of weakness; and glorify Him with [great] glorification."

2:116They say, "Allah has taken a son." Exalted is He! Rather, to Him belongs whatever is in the heavens and the earth. All are devoutly obedient to Him

10:68 They have said, "Allah has taken a son." Exalted is He; He is the [one] Free of need. To Him belongs whatever is in the heavens and whatever is in the earth. You have no authority for this [claim]. Do you say about Allah that which you do not know?

19
And they say, "The Most Merciful has taken [for Himself] a son." (88) You have done an atrocious thing. (89) The heavens almost rupture therefrom and the earth splits open and the mountains collapse in devastation (90) That they attribute to the Most Merciful a son. (91) And it is not appropriate for the Most Merciful that He should take a son. (92) There is no one in the heavens and earth but that he comes to the Most Merciful as a servant. (93) He has enumerated them and counted them a [full] counting. (94) And all of them are coming to Him on the Day of Resurrection alone. (95)
