My wife was ritually pure but she doubted whether her Wudu' was broken or not

Q 2: When we went to perform Tawaf-ul-Wada` (circumambulation of the Ka`bah on leaving Makkah), we performed it on the roof of Al-Masjid Al-Haram (the Sacred Mosque in Makkah) because of the over crowdedness around the Ka`bah. Having finished Tawaf-ul-Wada` of our Qiran Hajj (combining Hajj and `Umrah without a break in between), I asked my wife if she was pure (by means of performing Wudu` [ablution]) while performing Tawaf-ul-Wada`, but she did not remember whether she had performed Wudu' or not. Because the driver of the bus that would take us back to Al-Ta'if stipulated a specific period of time for our return, this prevented my wife from performing Tawaf-ul-Wada` again. Besides, we were very tired and our feet were badly wounded because of the long distance of Tawaf on the roof of Al-Masjid Al-Haram. Is it obligatory upon us to offer anything as a Fidyah (ransom) for doing so? A 2: If your wife was ritually pure (by means of performing Wudu') in this situation but she doubted whether her Wudu' was broken or not, the basic ruling is that she is regarded as ritually pure and her Tawaf is valid. If she was not pure (by means of not performing Wudu') and doubted whether she performed Wudu' or not, the basic ruling is that she is regarded as not ritually pure and consequently her Tawaf is invalid. In this case, she should have performed Wudu' and performed Tawaf again. Since you traveled to Ta'if before performing Tawaf again, she has to offer Dam (atonement required of a pilgrim for a willful violation of a prohibition or obligation while in the ritual state for Hajj and `Umrah) to be slaughtered in Makkah and the meat is to be distributed among the poor people as Tawaf-ul-Wada` is one of the obligatory acts of Hajj, which she did not perform as she performed it while she was not ritually pure.
