[Qur`an 3:75] Among the people of the Book (Jews and Christians as of today) there is one who, if you entrust him with a heap (of gold or silver), will give it back to you (fulfilling his trust); and among them there is one who, if you entrust him with a single dinar (a coin of gold), he will not give it back to you, unless you keep standing over him. This is because they have said, :There is no way we are to be faithful to these pagans. And they tell lies about Allah knowingly.
