Allah is not Yahweh

Yahweh has a son.  But, “Far be it from Allah, that he should have a son.”
1 John 5:11,12 And this is the testimony:  God has given to us eternal life, and that life is in his Son.  Someone who has the Son of God has life.  Someone who does not have the Son of God does not have life.
1 John 2:22,23 This is antichrist, someone denying the Father and the Son.   Everyone who denies the Son, does not have the Father either.  Someone who confesses the Son, has the Father as well.
