I find it hard to sleep after sahur. So, I'll think, alot.

God made it a huge point in the Quran that well-to-do people should donate to the needy. These words are imprinted for the past, present and future generations.

So, I guess He's implying that having needy people is inevitable. With that, too, He's implying that there will always be well-to-do people around.

Without needy people, well-to-do people won't give.
Without well-to-do people, needy people won't live.

So why should we give when we know that there's always needy people around?
Coz God made it a huge point(compulsory actually) to donate.
So why should needy people work knowing that there's always well-to-do people to give?
Coz God made it a huge point to work for yourself.

Human beans have to be told to do things.

God's a Genius.
