What is the explanation of the poetic verses related to a woman taking medication to prevent bleeding during the usual time of purity (Tuhr), accelerating menstruation before its due time, and the ruling on fasting and prayer in this situation?

The poet's saying: "If Hind drank to prevent blood from its usual time of purity, then rule; and that is a branch of what was heard, but if it is by hastening menstruation before its time, then you will not attain what you sought of absolution for an elder Khalil without doubt. And abstain from fasting and prayer during it, and they favored making them up, and you make up the fast completely." This means—and Allah knows best—that if a woman drank medicine to delay her menstruation from its usual time, and it was delayed, she is ruled to be pure. This is based on what was heard from Ibn Al-Qasim. However, if she intended by drinking medicine to hasten her menstruation before its time, she will not achieve her purpose, and what comes down from her is not considered menstruation. Therefore, she does not exit her waiting period with it, nor does she abandon prayer and fasting because of it. Scholars have favored her making up the prayer and fasting. The more correct view is that she only makes up the fasting as a precaution, and does not make up the prayer; for either what came to her was menstruation, in which case she is not required to pray nor make it up, or it was not menstruation, in which case she would have prayed while pure, so there is no reason for making it up, unless she abandoned prayer during the days of bleeding, in which case she should make it up due to the possibility of abandoning it without justification.
