Take alms out of their property, you would cleanse them and purify them thereby, and pray for them; surely your prayer is a relief to them; and Allah is Hearing, Knowing. (The Immunity 9.103)

And whatever alms you give or (whatever) vow you vow, surely Allah knows it; and the unjust shall have no helpers.

And do not swallow up your property among yourselves by false means, neither seek to gain access thereby to the judges, so that you may swallow up a part of the property of men wrongfully while you know.

If you disclose your alms, even then it is well done, but if you keep them secret, and give them to the poor, then that is better still for you; and this wipes off from you some of your evil deeds

And no blame is on you if he would not purify himself / And as to him who comes to you striving hard, / And he fears, / From him will you divert yourself.

Nay! surely it is an admonishment.
