Q: A woman is a Shafi and her husband as Hanafi. Shafis leave Muzdalifah after Maghrib and Hanafis after Fajr. The Shafi wife doesn’t have a Mahram to accompany her. What must she do?
A: A Shafi cannot leave Muzdalifah after Maghrib. Wuqoof at Muzdalifah begins in the second part of the night. The Shafi has to spend at least a short while at Muzdalifah during the second part of the night, and thereafter may depart. If the Shafi left before the second part of the night commenced, he has to return to fulfill the Wuqoof. If he did not do so before Fajr commenced, ‘Dumm’ will be compulsory. The Shafi wife must remain with her husband and leave Muzdalifah with him after Fajr. (Kitaabul Haj, Sheikh Muhammad Khateeb Al-Sharbeeni)
