Continuation of a question regarding the grammatical position of "those who" in the saying of Allah the Exalted: ((And He responds to those who believe and increases them of His bounty...))

The student: ...

The Shaykh : No, "those who" is the object of the verb... Also, the preferred view among us is that the One who responds is Allah, and that is His saying: If that were the case, He would have said: "and He will increase them" with the letter fā', [saying] "He responds to those who believe and do righteous deeds, and He will increase them when they respond." But since the conjunction that requires equality between the conjoined and the conjoined upon was used, what I said is not correct. Otherwise, He would have said: "He responds to those who believe and do righteous deeds, and He will increase them," meaning that because of their response, He increases them of His bounty... And regarding the response, Allah the Exalted said: meaning He responded to them.
