If a woman who has menstruation or post-partum bleeding attains purity before Fajr, but she does not perform Ghusl until after Fajr, will her fasting be valid?
All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu 'alyhi wa sallam, is His slave and Messenger.
Shaykh Ibn ‘Uthaymeen said: "Yes, if a woman attains purity from menstruation or post-partum bleeding before Fajr, but does not perform Ghusl until after Fajr, her fasting will be valid as she is among those who are under the obligation of fasting. This is the same as the one who was in a state of Janaabah and does not perform Ghusl before Fajr. In both cases fasting is valid. Allaah The Almighty Says (what means): {So now, have relations with them and seek that which Allaah has decreed for you. And eat and drink until the white thread of dawn becomes distinct to you from the black thread [of night].} [Quran 2:187] The fact that Allaah The Almighty has permitted sexual intercourse until Fajr entails that performing Ghusl would be after the first call to prayer for Fajr. Another proof of this is that ‘Aa’ishah, stated said that the Prophet, sallallaahu ‘alayhi wa sallam, would wake up in a state of Janaabah because of having had sexual intercourse with his wives and would fast on that day. This means that the Prophet, sallallaahu ‘alayhi wa sallam, would perform Ghusl after the time for Fajr had began."
Allaah Knows best
