Q. Can we do foreplay and light sex without letting any ejaculation while keeping fast?
بسم الله الرحمن الرحيم
(Fatwa: 1458/1313/B=12/1434)
Newly married couples are not allowed even to have light sex or foreplay while keeping fast. They are feared to fall in intercourse in case of intensity of sexual drive in foreplay. Doing intercourse in fast will be a major sin and it will require them to keep fast of 60 consecutive days as kaffarah (expiation). Therefore, you should avoid foreplay as well.
Allah knows Best!
