Expiation for an Oath Concerning a Past Matter
Machine translationRead the Arabic original
Question:
May Allah guide you. I swore an oath by Allah, but I was not truthful. Am I required to repeat it?
Answer:
If you swore to do something or to leave something undone, and you did it, then you owe an expiation. But if you swore about something in the past—such as saying "So-and-so did not come" or "So-and-so came," or "I did not do such-and-such" or "I did such-and-such"—a past matter—then if you were lying, you have committed a sin. This is the oath of al-Ghamus. Yes, and you do not owe an expiation. You must seek forgiveness and repent. Yes.
