“And woe to those who associate partners with Allah, who do not give zakāh.”

And He says:

“He recites His verses to them and purifies them.”

There is also purification from major sins, which brings piety to completion, as He says:

“So do not declare yourselves pure; He knows best who is mindful of Him.”

And He says:

“Have you not seen those who declare themselves pure? Rather, Allah purifies whom He wills, and they will not be wronged so much as the thread of a date stone.”

Thus, to declare someone pure is to attest to their piety. Self-purification also includes cleansing oneself, giving charity, and doing good, as He says:
