If a person swears not to have sexual relations with his wife for a certain period but breaks that oath, what must he do?

If a husband swears not to have intercourse with his wife for a certain period and breaks that oath, he must pay kaffarah:

1. Feeding 10 poor people
2.If unable, fasting for three consecutive days

Reference (Qur’an): “For those who swear not to approach their wives, a waiting period of four months is prescribed. If they return (to their wives), Allah is Most Forgiving, Most Merciful. But if they decide on divorce, Allah is All-Hearing, All-Knowing.” (Surah Al-Baqarah: 226–227)
