The individual prayer of one who separates from the congregation due to the urge to relieve oneself

Question:
He says: Honorable Shaykh, may Allah grant you success, is it permissible for one who has the urge to urinate or defecate, if that happens to him during the congregational prayer, to pray alone on the basis of this excuse?

Answer:
If he is unable to continue with the congregation, he proceeds, completes his prayer, and sits. . It is a mistake for him to enter the prayer while in this state. However, if he entered it and realized that he would not be able to continue with the imam, and he intended to leave, then this is an excuse and there is no harm, even though he committed a mistake in entering the prayer in the first place. Yes.
