What is the ruling on the invalidation of wudu' during the tawaf of 'Umrah?

Question:
The questioner says: I doubted my wudu' during my tawaf for 'Umrah. Is my 'Umrah valid or not?

Answer:
Yes. If you were in a state of ritual impurity, not on wudu', and you doubted whether you had performed wudu' or not, the default is that you did not perform wudu'. However, if the opposite is the case, you are certain that you are on wudu' but you doubt whether the wudu' was invalidated or not, the default is that the purity remains. The default is that the purity and wudu' remain, so your tawaf is valid. So, if one is not on wudu' and doubts whether he performed wudu' or not, the default is that he is not on wudu'. This is a rule. And if one is on wudu' with certainty and doubts whether his wudu' was invalidated, the default is that the purity remains. Yes.
