Definition of Laghu oath

Q 4: What is the Laghu oath?

A: "Laghu" is that a man takes an oath on something he thinks is like what he said, (Part No. 23; Page No. 75) only to find that it is other than what he said. For example when a man swears that so and so is in the house, then he finds that they are not; or when he says, 'By Allah, no" and "By Allah, yes" without intending the meaning of his swearing.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
