The ruling on one who doubts the invalidation of his wudu' during 'Umrah and is certain of it after completing it?

Question : The questioner says: This question confuses me. I prayed 'Isha', and while praying 'Isha, I felt something coming out from the front, but I said it was from Shaytan. After the prayer, I performed the rites of 'Umrah. When I finished the 'Umrah and went to the lodging, I became certain that it was madhi. I do not know if I should repeat the 'Umrah, knowing that I am not from the people of Makkah. If the ruling requires me to repeat it, from where do I enter ihram? Knowing that I am from the north, and is there a fidyah on me?

Answer : The answer: There is nothing on you, because you are not certain that what came out of you was before the tawaf, and the default is that it was after the tawaf. This is a useful rule for the student of knowledge: if one doubts whether the invalidator was before the act or after it, the default is that it was after it. So if a man performed wudu' and prayed, and after the prayer he saw a trace of hadath on his garment and doubts whether it was before the prayer or after it, it is considered to be after the prayer. Based on this, we say to this brother who did not know of the invalidator of wudu' until after the tawaf: there is nothing on you, because there is a strong possibility that it occurred after the tawaf. Yes.
