The ruling on a man having intercourse with his wife while fasting a voluntary fast
Machine translationRead the Arabic original
Question:
May Allah bless you. This questioner says, may Allah preserve you: A man gave his wife permission to fast a voluntary fast, and during the day he desired to have intercourse with her. Is that permissible for him?
Answer:
Yes, it is permissible for him to do so; because a voluntary fast is not required to be completed. It is permissible for a person to break his fast during the day for eating, drinking, or intercourse. It is not required to complete it. This applies only to the obligatory fast, such as the fast of Ramadan, making up a missed fast of Ramadan, a vow, or an expiation. It is not permissible to break or interrupt an obligatory fast. As for a voluntary fast, there is no harm in breaking it.
