If a morsel falls from the food of someone else, such as his son or his wife, is it permissible for him to eat it as a way of thanking Allah for His blessing?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: If a morsel falls from the food of someone else, such as his son or his wife, is it permissible for him to eat it as a way of thanking Allah for His blessing?

Answer:
If he does not dislike it, there is no harm. But if he dislikes it, the Prophet (peace and blessings be upon him) only commanded the owner of the morsel to do so. As for anyone else, it is up to him. If he does not dislike it, that is good, as it is a way of honoring the blessing. But if he dislikes it, then no.
