And whatever you give for interest to increase within the wealth of people will not increase with Allah. But what you give in zakah, desiring the countenance of Allah - those are the multipliers.
Those who consume interest cannot stand [on the Day of Resurrection] except as one stands who is being beaten by Satan into insanity. That is because they say, "Trade is [just] like interest." But Allah has permitted trade and has forbidden interest. So whoever has received an admonition from his Lord and desists may have what is past, and his affair rests with Allah. But whoever returns to [dealing in interest or usury] - those are the companions of the Fire; they will abide eternally therein.
لِيُنفِق ذو سَعَةٍ مِن سَعَتِهِ ۖ وَمَن قُدِرَ عَلَيهِ رِزقُهُ فَليُنفِق مِمّا ءاتىٰهُ اللَّهُ ۚ لا يُكَلِّفُ اللَّهُ نَفسًا إِلّا ما ءاتىٰها ۚ سَيَجعَلُ اللَّهُ بَعدَ عُسرٍ يُسرًا
آ
Let a man of wealth spend from his wealth, and he whose provision is restricted - let him spend from what Allah has given him. Allah does not charge a soul except [according to] what He has given it. Allah will bring about, after hardship, ease.
And do not give the weak-minded your property, which Allah has made a means of sustenance for you, but provide for them with it and clothe them and speak to them words of appropriate kindness.
Who is it that would loan Allah a goodly loan so He may multiply it for him many times over? And it is Allah who withholds and grants abundance, and to Him you will be returned.
O you who have believed, spend from the good things which you have earned and from that which We have produced for you from the earth. And do not aim toward the defective therefrom, spending [from that] while you would not take it [yourself] except with closed eyes. And know that Allah is Free of need and Praiseworthy.
And do not approach the orphan's property except in a way that is best until he reaches maturity. And give full measure and weight in justice. We do not charge any soul except [with that within] its capacity. And when you testify, be just, even if [it concerns] a near relative. And the covenant of Allah fulfill. This has He instructed you that you may remember.
Allah presents an example: a slave [who is] owned and unable to do a thing and he to whom We have provided from Us good provision, so he spends from it secretly and publicly. Can they be equal? Praise to Allah! But most of them do not know.
Say [to them], "If you possessed the depositories of the mercy of my Lord, then you would withhold out of fear of spending." And ever has man been stingy.
