Is it permissible for the one in i'tikaf (spiritual retreat in the mosque) to leave the mosque to rest?

Question:
A man is in i'tikaf; is it permissible for him to go out for an appointment he made before entering i'tikaf?

Answer:
In the name of Allah, the Most Gracious, the Most Merciful. All praise is due to Allah, Lord of the worlds, and may Allah send prayers and blessings upon our Prophet Muhammad. I'tikaf means staying in the mosque for the worship of Allah and leaving the works of this world, dedicating oneself to the works of the Hereafter. If he has an appointment he made with someone before the i'tikaf, let him apologize to him and postpone it to after the festival, if the other person accepts the postponement. But if the other person does not accept the postponement and it is a necessary task, there is no harm in him going out to complete it, but he should strive to return quickly to his i'tikaf. He should not be tied to other works, nor to other appointments and tasks after he has entered i'tikaf. Yes.
