If a woman does not find a mahram, is Hajj obligatory upon her?

The Shaykh : Now, if a woman does not find a mahram, then Hajj is not obligatory upon her, because she has no way to reach it, whether by Shari'ah or by nature. She is able to travel without a mahram, but she is prohibited from doing so by the Shari'ah. We have mentioned to you previously that the scholars differ on whether the presence of a mahram is a condition for the obligation or a condition for the performance. We said that the apparent view is that it is a condition for the obligation. Yes.
