And whatever you have given out of usury-interest (3:130) to have-gains-of-interest within the wealth of people will not have gains-of-interest with Allah.
But whatever you have given out of Zakat (donation), desiring the Face of Allah – then they are those who are the Doublers/Multipliers.
Rule 1. Soul-Cleansing Zakat
Rule 2. Giving Zakat – Donation
Zakat itself is a form of soul-cleansing (tazakkā f.5 v.) as said in 35:18 through Salah-Prayer and that is also said in 87:14-15 (87:14 tazakkā & 87:15 faṣallā).
You will notice that, Salah-Prayer and Zakah are mentioned together in most cases in the Quran.
4:49 Did you not see the one who ascribe themselves/their souls cleansed/pure (yuzakkūna anfusahum)? Rather, Allah cleanses/purifies (yuzakkī) whoever He wills, and they will not be wronged a single date-thread.
53:32 …So do not ascribe yourselves/your souls cleansed/pure; He is most knowing with whoever fears/is god-conscious.
24:28 And if you do not find anyone therein, do not enter them until permission has been given you. And if it is said to you, “Go back,” then go back; it is purer/azkā for you. And Allah is Knowing of what you do.
24:30 Tell the believing men to reduce [some] of their vision and guard their private parts. That is purer for them. Indeed, Allah is Acquainted with what they do.
You can give it by spreading the Message/Book of Allah and the Wisdom like Messengers do in 2:129, 2:151, 3:164, & 62:2, it will yuZakkīhim – cleanse their souls.
9:103 <Take from their wealth/monies (amwālihim) a Charity (ṣadaqatan), purifying them (tuṭahhiruhum) and cleansing them (watuZakkīhim) with it.
