Is a woman sinful for delaying prayer if she menstruates before performing it, while expecting menstruation at any moment?

The prayer time is extended from its beginning to its end. However, if a Muslim believes a hindrance will prevent them from praying at the end of its time (such as death or menstruation), they must hasten to pray before this hindrance occurs; otherwise, they would be disobedient by delaying it. So, whoever expects menstruation to begin must hasten to pray and not delay it. As for one who does not intend to perform the prayer within its time, this is an intentional abandonment of prayer. In this case, missed prayers must be made up.
