Allah sets forth a parable: (consider) a slave, the property of another, (who) has no power over anything, and one whom We have granted from Ourselves a goodly sustenance so he spends from it secretly and openly; are the two alike? (All) praise is due to Allah! Nay, most of them do not know.

And certainly We have explained in this Quran every kind of example, and man is most of all given to contention.
