The Gross Blasphemy
[10:68] They said, “GOD has begotten a son!” Be He glorified. He is the Most Rich. To Him belongs everything in the heavens and everything on earth. You have no proof to support such a blasphemy. Are you saying about GOD what you do not know?
[10:69] Proclaim: “Those who fabricate lies about GOD will never succeed.”
[10:70] They get their temporary share in this world, then to us is their ultimate return, then we commit them to severe retribution for their disbelieving.
In verse 10:68 what is the relation with God not having a son, having to do with God being “Most Rich”?
To many having children is a sign of wealth. God is stating that to Him belongs everything that He does not need to beget a son as a sign of wealth.
10:69 does the succeed mean only in the Hereafter?
From verse 70 it indicates that they will get “their temporary share in this world,” inferring that the success is referring to the Hereafter.
Gross Blasphemy
[2:116] They said, “GOD has begotten a son!” Be He glorified; never! To Him belongs everything in the heavens and the earth; all are subservient to Him. [2:117] The Initiator of the heavens and the earth: to have anything done, He simply says to it, “Be,” and it is.
