What is the ruling regarding the landlord's anger and his interruption of the visiting woman's husband, accusing him of entering his house without permission, based on his coming to take food that his wife had prepared with the hostess?

As long as the man did not enter the house, he has not committed anything unlawful, nor has he trespassed on the right of the homeowner. Therefore, the homeowner has no right to boycott the man for this reason. Jealousy over one's family is commendable, as long as it does not exceed the bounds of moderation.
