Doubting the validity of one's Wudu' while performing Tawaf

Q: I performed Ifrad Hajj (performing Hajj only) this year but during Tawaf-ul-Qudum (circumambulation of the Ka`bah on arrival in Makkah) I felt some drops of Madhy (thin white viscid fluid secreted due to sexual thoughts or desire). I became confused because of some opinions that having Taharah (ritual purification) is not a condition for Tawaf (circumambulation of the Ka`bah) and I completed my Tawaf. I went to the toilet to check and renew my Wudu' (ablution) to perform two Rak`ahs (unit of Prayer) behind Maqam Ibrahim (the Station of Ibrahim) and do the Sa`y (going between Safa and Marwah during Hajj and `Umrah). However, I found nothing but I was not sure if there was no Madhy from the beginning or that it dried out and I did not see it, I do not know. Please, illustrate for us the ruling on this Tawaf and is there anything due upon me? May Allah reward you with the best!Also, I did not combine between Tawaf-ul-Wada` (circumambulation of the Ka`bah on leaving Makkah) and Tawaf-ul-Ifadah (final obligatory circumambulation of the Ka`bah in Hajj) but I performed each one alone and while I was performing it I felt the same thing that I felt in Tawaf-ul-Qudum (circumambulation of the Ka`bah on arrival in Makkah) again. I remembered that I did not find anything, so I took it as certainty and completed Tawaf-ul-Wada` and offered two Rak`ahs behind the Maqam. Then, I entered the toilet after I finished and I found nothing. Please, show us the ruling, may Allah reward you with the best!

A: If you had started Tawaf while you were sure about your purity then you doubted the validity of your Wudu' during Tawaf and completed the Tawaf, your Tawaf is valid because Taharah (ritual purification) was based on certainty while the others were merely doubts, and certainty is not cancelled by doubts. The Prophet (peace be upon him) said to the person who raised doubts about the occurrence of Hadath (ritual impurity that invalidates ablution) during Prayer: He should not leave unless he hears a sound or perceives a smell (of passing wind). As for (Part No. 10; Page No. 245) Tawaf-ul-Wada` (circumambulation of the Ka`bah on leaving Makkah), it is permissible to intend it with Tawaf-ul-Ifadah (final obligatory circumambulation of the Ka`bah in Hajj) if a pilgrim is leaving directly after it. The Prophet (peace be upon him) said: and every person will get the reward according to what he has intended. Moreover, this is rightfully considered as the last thing to be witnessed from Al-Bayt (Ka`bah). However, if a pilgrim will stay after Tawaf-ul-Ifadah (final obligatory circumambulation of the Ka`bah in Hajj), it is obligatory to perform Tawaf-ul-Wada` upon leaving.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
