In this fatwa:
Scholars have unanimously agreed that it is mandatory for menstruating women and women who had post childbirth bleeding to break their fast and to make up for the days they missed later on after Ramadan.
In his book Fiqh-us-Sunnah, the late Egyptian scholar Sheikh Sayyed Sabiq (may Allah bless his soul) states:
Scholars have unanimously agreed that it is mandatory for menstruating women and women who had post childbirth bleeding to break their fast and to make up for the days they missed later on after Ramadan.
Al-Bukhari and Muslim record that Aishah (may Allah be pleased with her) said, “When we would have our periods during the lifetime of the Prophet (peace and blessings be upon him), we were ordered to make up for the days of fasting that we had missed but were not ordered to make up for the prayers we had missed.” (An-Nasa’i)
