What is the grammatical analysis (إعراب) of the word “Allah” (لفظ الجلالة) in His, the Almighty’s, saying: "And were it not for Allah's repelling of some people by means of others"?

The Glorious Name (Allah) in the verse is grammatically in the genitive case by لفظ (pronunciation) due to annexation, but in the nominative case by معنى (meaning) due to its being the doer of the action. It can be parsed either as a mudaf ilayh (annexed noun) in the genitive case, or as a fa‘il (doer) that is in the genitive case by لفظ and in the nominative case by محل (grammatical position), resulting from the annexation of the verbal noun to its agent.
