(2:271) If you disclose your charitable expenditures, they are good; but if you conceal them and give them to the poor, it is better for you, and He will remove from you some of your misdeeds [thereby]. And Allah, with what you do, is [fully] Acquainted. (2:272) Not upon you, [O Muhammad], is [responsibility for] their guidance, but Allah guides whom He wills. And whatever good you [believers] spend is for yourselves, and you do not spend except seeking the countenance of Allah. And whatever you spend of good - it will be fully repaid to you, and you will not be wronged. (2:273) [Charity is] for the poor who have been restricted for the cause of Allah, unable to move about in the land. An ignorant [person] would think them self-sufficient because of their restraint, but you will know them by their [characteristic] sign. They do not ask people persistently [or at all]. And whatever you spend of good - indeed, Allah is Knowing of it. (2:274) Those who spend their wealth [in Allah `s way] by night and by day, secretly and publicly - they will have their reward with their Lord. And no fear will there be concerning them, nor will they grieve. (2:275) 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. (2:276) Allah destroys interest and gives increase for charities. And Allah does not like every sinning disbeliever. (2:277) Indeed, those who believe and do righteous deeds and establish prayer and give zakah will have their reward with their Lord, and there will be no fear concerning them, nor will they grieve.
