A student asked his teacher: "If the shaytan (devil) is locked up during
Ramadan, why do people still do bad things?"
Teacher answered: "What happens when you stir a cup of coffee for a long
time? After you take the spoon out the coffee continues to stir on its own,
right? Shaytan is that stirrer and we are his coffee. Our bad habits
continue to stir even when he is away."
