“Those who hoard gold and silver” (al-Tawbah 9:34).
A report from Ibn ʿUmar connects the warning about hoarding with the ruling of zakāh and uses language of precedence. That need not mean the verse was chronologically revealed before zakāh was prescribed: the late date of Sūrat al-Tawbah and the earlier obligation of zakāh stand against such an inference.
The better distinction is between a general moral-legal concern and its more detailed legal specification. Priority here can be explanatory or logical, rather than a historical chronology.
