What is the ruling regarding the use of contraceptive pills/medicine to prevent menstruation during Ramadhaan to avoid making qadha?

Answer

It is not permissible for women to use poison and harmful substances or any substance whatsoever to prevent their haidh periods whether in Ramadhaan or in any other month. It is not permissible for them to violate the natural law which Allah Ta'ala has created for the expulsion of the filth of haidh from their bodies. Unnatural storing of haidh in the body is vile and extremely harmful and haraam. By resorting to these haraam methods, they are storing extremely harmful najaasat inside their bodies. It causes even mental imbalance. The consequences of this evil and unnatural action are injurious. Their monthly periods will go haywire. Furthermore, a host of other diseases and sicknesses could develop and doctors will not know what the causes are nor be able to prescribe correct medication. Allah's Law dictates that women MUST abstain from fasting during Ramadhaan for the duration of their haidh period, and to make qadha afterwards. This is the Law of Allah for them. It is abominable for women to act in flagrant violation of this Decree of Allah Azza Wa Jal. The haidh condition is not an accident. It is by divine decree.
