What is the secret behind the sealing of verse 44 from Surat Fatir with the two forms of knowledge and power?

The secret behind concluding verse 44 of Surah Fatir with knowledge and power is that Allah mentions in it the punishment of the deniers and clarifies that nothing in the heavens or on earth can incapacitate Him. This is because He is All-Knowing of everything therein and All-Capable over it. And whoever claims not to be incapacitated by anything while lacking these two attributes, or one of them, is a liar.
