What is the ruling on a woman using pills to delay her period in Ramadan

Question : The sister says: O Shaykh, we heard from your eminence that if a woman gets her period in Ramadan, she does not receive reward, and therefore she says: We were compelled to take pills to prevent the monthly period, so please guide us in light of this question?

Answer : I say that if a woman gets her menstruation in Ramadan, she does not fast, as is well known, but she makes it up.
And she has the reward of fasting, but it is not like the reward of the one who fasts in Ramadan. The evidence for this is the saying of the Prophet (peace and blessings be upon him) regarding the woman that she is deficient in religion. They said: What is the deficiency in her religion? He said: Is it not that when she menstruates, she does not pray and does not fast? So the Prophet (peace and blessings be upon him) — we ask Allah for safety — made that a deficiency in her religion, except that it is a deficiency for which she is not blamed, because she only broke her fast by the command of Allah. So she, from this aspect, meaning from the aspect of obedience to Allah the Exalted, is rewarded.
As for taking the pills in order for the period not to come down, this is a mistake. Because menstruation is natural blood that Allah has decreed for the daughters of Adam. And restraining it will undoubtedly be harmful. Because it is taking the body out of its nature.
Then it reached me from trustworthy doctors that there is much harm in it; they wrote to me about it. Therefore, we forbid the woman from taking these pills in order to fast in Ramadan.
