Lying is lawful in some cases : Know that falsehood is not unlawful for its own sake but it is unlawful for the harm caused to the person with whom falsehood is spoken or harm to other persons.

Sometimes false speaking becomes compulsory. In some places, false- speaking is better than speaking the truth. To save a person from unjust
oppression or unjust killing is must, so lying only becomes compulsory to lie. If then the truth is spoken, a life will perish in the hand of an oppressor.

To compromise between two parties and to preserve good will between two co-wives, false speaking is lawful. He who settles disputes between two parties is not a liar. The lie which is spoken to please a wife is not recorded.
