What is the ruling on a man who enjoyed himself with his wife during the day in Ramadan, but without ejaculation or penetration?

Question:
The questioner says: A man enjoyed himself with his wife during the day in Ramadan, but without ejaculation or penetration, for a period of nine days. What is the ruling, and what should he do?

Answer:
If he enjoyed himself without penetration and without ejaculation, then he has committed a sin, but his fast is valid. This is because intercourse did not occur, and ejaculation of semen did not occur, so his fast is valid. However, he has committed a sin through the lewdness, which is the preliminaries to intercourse, such as touching, kissing, and talking. The fasting person commits a sin through this. However, his fast is not invalidated by it. The fast is not invalidated except by one of two things: either the ejaculation of semen, or intercourse, which is penetration into the private part.
