God does not punish you but for what you swear in earnest. The expiation (for breaking an oath) is feeding ten persons who are poor, with food that you give your own families, or clothing them, or freeing a slave. But he who cannot do so should fast for three days. This is the expiation for an oath when you have sworn it. So abide by your oaths. Thus God makes His commandments clear to you: You may perhaps be grateful.
