What rituals can a menstruating pilgrim perform at the miqat while awaiting purity, and does she perform the remaining rituals alone after achieving purity if her husband has already completed his 'Umrah?

If a menstruating woman reaches the Miqat and intends to perform Hajj al-Tamattu‘, she must enter into the state of ihram for Umrah and perform all the rituals a pilgrim does, except for circumambulating the Kaaba, until she becomes pure. When she becomes pure, she should perform the circumambulation (tawaf), the going back and forth between Safa and Marwah (sa‘i), and then shorten her hair to complete her Umrah. It is preferable for her husband to accompany her during the tawaf and sa‘i to assist her, but there is no harm if she performs them alone.
