What is the ruling on saying: "Allah and the Prophet are enough for me against every oppressor and aggressor"?

It is not permissible to associate the Prophet (peace be upon him) with hasb (sufficiency), as sufficiency, providence, reliance, desire, and devotion belong to Allah alone, just as worship, piety, prostration, vows, and oaths are exclusively for Him, the Almighty.

Allah has distinguished between hasb (sufficiency) and support, making sufficiency exclusive to Him while granting support through His victory and His servants. He has praised the people of monotheism and reliance for dedicating sufficiency to Him alone, without saying "Allah and His Messenger are sufficient for us," but rather stating "Allah is sufficient for us," because Allah alone is the one who suffices His servant and has not associated anyone with Him in this regard.
