If one forgets the prescribed dhikr when entering the place of relief, does he go out and recite the dhikr, or what does he do?

Question:
He says: Honorable Shaykh, may Allah grant you success, if I entered the place of relief and forgot the prescribed dhikr, do I go out and say the dhikr, then enter a second time?

Answer:
No, no, no, it is not necessary. Your forgetting is excused; if a Muslim forgets, he is excused, because he did not intentionally leave off the dhikr.
