Lend unto Allah a goodly loan. Whatever good you shall forward on your behalf you shall find it with Allah, as better and richer in reward. [al-Muzzammil 73: 20.]

Be generous, therefore, for whatever you spend on yourself is only for your temporary sustenance while whatever you spend in the way of Allah is an investment in your future for which will provide everlasting sustenance. Seek to invest in others for your own benefit with whatever Allah has endowed you.
