Allah criticizes those who claim that He has, {...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, {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. {No warrant have you for this} Meaning, you have no proof for the lies and falsehood that you claim, {Do you say against Allah what you know not.} This is a severe threat and a firm warning. Similarly, Allah threatened and said: {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]. Then Allah warned the liars that fabricated the claim that He has begotten a son. He warned that they will not succeed, never prospering in this world or in the Hereafter. In this world Allah will lead them, step-by-step, to their ruin. He will give them respite and put up with them for a while. He will allow them to have little enjoyment, {then in the end We shall oblige them to (enter) a great torment.} [31:24]. As Allah said here: {(A brief) enjoyment in this world!} meaning, only a short period, {and then unto Us will be their return} on the Day of Resurrection; {Then We shall make them taste the severest torment because they used to disbelieve.} meaning, 'We shall make them taste the painful punishment because of their Kufr and lies about Allah.'
