Does one repeat the tawaf if he finds ritual impurity in his garment after completing it?

Question:
He says: In my two 'Umrahs last year in Ramadan, after I finished the sa'y, I found ritual impurity in my ihram garments, so I changed my ihram garments and repeated the tawaf and sa'y a second time.

Answer:
You are not required to repeat it as long as you did not know that it occurred during the tawaf. The default is purity, and the occurrence of a state of ritual impurity after completing the act of worship does not invalidate it, because it may have occurred after he had finished, and he does not know. The default is validity, and the default is the continuation of purity, and praise be to Allah, unless he knows one hundred percent that he performed the tawaf while having ritual impurity on him, or that he was in a state of ritual impurity. Yes.
