Does feeding a visitor's child a piece of candy constitute a violation of the husband's oath of divorce if something is taken out of the house without his knowledge? And is it permissible for the husband to change the wording of his oath of divorce?

The consequence of recklessness and trifling with oaths of divorce is the destruction of the marital bond and falling into distress and hardship. Feeding visitors in the house does not contradict the husband's oath, because his oath was to expel [her] from the house, so he does not break his oath unless he expels [her]. The husband's forgetting his oath is not considered as long as you remember it. The matter must be referred to the Sharia courts, because swearing by divorce is a matter sobre el cual los juristas difieren. Some consider it a contingent divorce, while others consider it an oath for which expiation is due upon breaking it. This latter opinion is what is acted upon in many Sharia courts.
