For those who spend their wealth in the Cause of God...
For those who spend their wealth in the Cause of God, and follow not up their gifts with reminders or with injury, their reward is with their Lord; on them shall be no fear, nor shall they grieve.” ( 2:261,262). God explains that the money we spend in His Cause will be doubled and multiplied for us, and that this will be profitable for us both now and in the Hereafter.
The only condition, however, that God sets for the attainment of this reward, is that the benefactor should not remind those who receive his support of his benefaction to them. The Qur'an urges people to acts of charity and makes it attractive to believers by describing charity as a goodly loan. He says:. “Who is he that will lend God a goodly loan, which God will double unto his credit and multiply many times? It is God that gives (you) Want or Plenty, and to Him shall be your return” (2: 245).
God shows extreme kindness by making charity a sort of goodly loan paid to Him. It is the needy who ask for loans, whereas God, to Whom "belongs the dominion of heavens and the earth, and all in between", is not in need of a loan from His creatures. But the mode of expression is set in this form mainly to attract believrs into giving charity, thereby securing a means for the poor to achieve what they need, and for the more fortunate to achieve the pleasure of Allah.
The benefit of this loan goes back to human beings themselves, and they enjoy the fruits of it in this world as well as in the Hereafter. Such is the mercy of Allah. The Qur'an also describes the spending of money in the Cause of God as a profitable trade that benefits its owner on the Day of Resurrection: “O you who believe! Shall I lead you to commerce that saves you from a grievous Penalty?
You should believe in God and His Apostle, and should strive (your utmost) in the cause of God, with your property and your lives. That will be best for you, if you but knew” (61: 1011). Many Ahadith also talk about the benefit of helping others: • Charity keeps away from its givers, the heat of the grave, and on the Day of Judgement, the believer will be in the shade of his charity.
Holy Prophet (S) • Allah smiles at the person who stretches out his hand to give charity, and whoever Allah smiles at is forgiven. Holy Prophet (S) • Guard yourselves from the fire (through charity) even if by a date, for surely Allah will raise it (cause it to grow), just as one of you raises his foal . . . until it becomes greater than a huge mountain.
