What is the ruling for a person performing 'Umrah if a hair falls out unintentionally?

Question:
He says: While performing sa'y (walking between al-Safa and al-Marwah), during the sixth lap, I felt the urge to urinate. When I put my hand inside my ihram, I found nothing, but a hair from my belly came out with my hand. I performed wudu' (ablution) and remembered that I had not prayed the two rak'ahs at Maqam Ibrahim, so I prayed the two rak'ahs. Then I started the sa'y again. What is the ruling on my actions? Is the 'Umrah valid?

Answer:
The 'Umrah is valid as long as you completed the tawaf (circumambulation) and the sa'y in full. However, your action was a mistake, because purity is not a condition for sa'y, even if you are not in a state of wudu'. The sa'y is valid. Purity is only required for the tawaf around the House. As for sa'y, purity is recommended (mustahabb) in it. If you had completed the sa'y, it would have been valid. Yes.
