It is clear that a society in which most of the people are hungry and poor, and some are very wealthy cannot last very long. Undoubtedly there will be stress, animosities or even fights in such a society. A careful examination of the verses of the Qur’an on this issue clearly indicates that Islam aims to eliminate unjust social differences between the rich and the poor.
It aims to establish certain means by which the standard of living of the poor people can be elevated to a point at which they can at least benefit from minimum living necessities. To achieve this goal Islam has absolutely forbidden usury. It has also established certain obligatory taxes such as the alms-tax and the one-fifth levy. It has also encouraged many voluntary forms of charity to help achieve this goal.
Motivations for Charity The Qur’an clearly shows the various results of charity using various examples and drawing similitude.
Cancel not your charity by reminders of your generosity or by injury, - like those who spend their substance to be seen of men, but believe neither in God nor in the Last Day. They are in parable like a hard, barren rock, on which is a little soil: on it falls heavy rain, which leaves it (just) a bare stone. They will be able to do nothing with aught they have earned.
And God guideth not those who reject faith.” [The Holy Qur’an, al-Baqarah 2:264] Consider a hard rock covered by a thin layer of dirt. If seeds are planted in the dirt, there is plenty of good weather and sunshine, and then there is a heavy rainfall, the seeds will be washed off along with the dirt. The rock is so hard that the seed cannot grow on it and the barren hard appearance of the rock will appear again.
This does not happen because the sunshine, the good climate or the rains have had a bad effect. Rather it is because the place was not suitable for growth. It has had a good appearance, but it has been solid hardness beneath.
