Is it جائز to use الأدوية to delay menstruation for الحج?

It is جائز for a woman to use الأدوية to delay her menstrual cycle in order to perform الحج rituals without interruption, provided there is no medical harm. الشيخ ابن عثيمين stated: 'There is no harm in a woman taking pills to prevent her period during الحج or رمضان, on condition that this does not harm her health, as confirmed by a trustworthy doctor.' الشيخ ابن باز held a similar view. However, if menstruation begins despite الأدوية, the woman follows the rulings of menstruation during الحج.
