Is it permissible to take pills to delay haidh in order to fast the full month of Ramadhaan?

Answer

Interfering with the natural process created by Allah Ta'ala is extremely harmful and not permissible. Haidh is impurity. Allah Ta'ala has created a natural mechanism in the woman's body for the discharge of this harmful impurity. The purity has to be expelled, not retained inside the body beyond its natural period. It should be understood, that the consequences of interfering with the natural system and retaining the filth inside the body leads to multiple health complications. The Qur'aan describes such interference with Allah's creation as Taghyeer li khalqillaah (changing the natural creation of Allah) effected by shaitaan'. It is therefore not permissible to take medication for delaying haidh. The Shariah has ruled that women should make qadha of the fasts which they miss during Ramadhaan. They should not attempt to supersede the Shariah. Allah Ta'ala is the Creator. He knows what He creates and does.
