Allah is Far Above taking a Wife or having Children
Allah tells;
قالوا اتخذ الله ولدا
They say: "Allah has begotten a son.''
Allah criticizes those who claim that He has,
ولدا
سبحانه هو الغني
...begotten a son. Glory is to Him! He is Rich (Free of all needs).
He is Greater than that and above it. He is Self-Sufficient, free of want or need of anything. Everything else is in desperate need of Him,
له ما في السماوات وما في اﻻرض
His is all that is in the heavens and all that is in the earth.
So how can He have a son from what He has created! Everything and everyone belongs to Him and is His servant.
إن عندكم من سلطان بهذا
No warrant have you for this,
Meaning, you have no proof for the lies and falsehood that you claim,
أتقولون على الله ما ﻻ تعلمون
Do you say against Allah what you know not.
This is a severe threat and a firm warning.
Similarly, Allah threatened and said:
وقالوا اتخذ الرحمن ولدا
لقد جيتم شييا إدا
تكاد السموت يتفطرن منه وتنشق اﻻرض وتخر الجبال هدا
أن دعوا للرحمن ولدا
وما ينبغى للرحمن أن يتخذ ولدا
إن كل من فى السموت واﻻرض إﻻ آتى الرحمن عبدا
لقد أحصهم وعدهم عدا
وكلهم ءاتيه يوم القيمة فردا
And they say: "The Most Gracious has begotten a son.''
Indeed you have brought forth a terribly evil thing. Whereby the heavens are almost torn, and the earth is split asunder, and the mountains fall in ruins, that they ascribe a son to the Most Gracious. But it is not suitable for the Most Gracious that He should beget a son.
There is none in the heavens and the earth but comes unto the Most Gracious as a servant. Verily, He knows each one of them, and has counted them a full counting. And everyone of them will come to Him alone on the Day of Resurrection. (19:88-95)
