When we look at all that we have been given by God -- health, wealth, family, residence, job, and all the rest -- it is not a question of whether we deserve any of it or not.
The real point is that we were paid. God paid us. He gave us all these things.
And we took those things and pocketed them. We collected payments and cashed the checks that came from God.
Now we are in debt. And that debt must be paid back.
If we don't, it will be collected from us by force. And the history of Muslims is just that: God trying to collect his debt from Muslims.
One way to pay God back for all he gave us is to work for him.
To find out how to do this is what the Qur'an was sent down into this world to tell us.
And to show us in practice how to do any of it is what the Sunnat -- the way and the entire life -- of Prophet Muhammad, Sallallahu Alaihi wa Sallam, is all about.
