Question:
Would it be permissible to take birth control to stop her menstruation
in order to avoid menstruation during Hajj?
Answer:
Walaikum assalam wa rahmatullah,
1. Birth control pills are in of themselves permitted. They are, thus,
permitted to take�though superior to avoid to the extent of their
harm.
2. It is permitted to take such birth control pills�and other
period-delaying medication�to delay one�s period during one�s Hajj.
However, it is best to let one�s period run its course. The only
action of Hajj directly affected by menstruation if tawaf, and this is
only significant with regards to the main obligatory tawaf (tawaf
al-ziyara), which is not permitted to be performed in a state of major
ritual impurity, and if unperformed leaves one�s Hajj unperformed and
keeps one in a state of ihram. [Ibn Abidin, Radd al-Muhtar]
Wassalam,
