Moreover, Ahl al-Sunnah believe in the divine decree: whatever Allah wills comes to pass, whatever He does not will does not come to pass, and guidance is granted by His grace.
The Qadarīyya say:
He is obligated to do for every servant whatever they themselves deem obligatory upon Him, and He is forbidden to do the opposite. They thus impose certain obligations upon Him and forbid [Him] (1) certain things, although He has not imposed those obligations upon Himself, nor has their obligatoriness been established by revealed law or reason. They then report (2) that those who do not impose these obligations upon Him say, “Allah fails to fulfill what is obligatory.” This is a deceptive and distorted representation of their position.
[The doctrine of these Qadarīyya is fundamentally based on likening Allah to His creation with respect to actions. They therefore hold that whatever is good when done by Him is good when done by a servant, and whatever is reprehensible when done by a servant is reprehensible when done by Him. This is a false equation] (3).
[Section: Refuting the Rāfidī’s Claim That Allah Does Not Act for Any Purpose or Wisdom]
As for his statement:
“They maintained that He does not act for any purpose; rather, none of His acts serves any purpose whatsoever or embodies any wisdom at all (4).”
