When a servant is characterized by what belongs to God, even if it is lawful, which is fasting, God makes him forget that he is fasting, and places him in a position and state that spoils his fasting, alerting him that this truth is only characterized by God, divine jealousy, to review what he is. He has a kind of participation, and when the slave did not intend to do so and did not violate the sanctity of the person responsible, the fulfillment of the obligation, expiation, and intercourse are forfeited. Its meaning is known in the case of one who has intercourse intentionally.
