If the woman performing tamattu' menstruates before the tawaf for 'Umrah and fears missing the Hajj

Question : If the woman performing tamattu' menstruates before the tawaf for 'Umrah and fears missing the Hajj, or if someone else fears that, she enters the state of ihram for Hajj along with the 'Umrah and becomes a qarin (one who combines 'Umrah and Hajj in one ihram). This is based on the hadith of 'A'ishah, and because it is permissible to add Hajj to 'Umrah without an excuse, so it is even more permissible when there is a fear of missing the Hajj.

Answer : There is no difficulty in this, but we say that in this case, if this is his obligatory duty, it is obligatory for him to add Hajj to the 'Umrah so that he does not miss the Hajj. Accordingly, the benefit of this section is that if the one who entered ihram for 'Umrah fears missing the Hajj, and this is his obligatory duty, it is obligatory for him to add Hajj to the 'Umrah and become a qarin. However, if this is not his obligatory duty, he may remain with his 'Umrah even if he misses the Hajj, because it is a voluntary act.
