Women’s Fasting During Periods
I understand that Islam either corrected incorrect practices or provided new rules on Sunnat. This is true. The Quran deals with exceptions but does not raise the point on women as “taharat” is the pre-condition. Quran is not the only source of religion. Prophet Muhammad SAW gave us deen through Quran as well as Sunnah, both of which have been conclusively transmitted to us through ijma and tawatur. We know from ijma and tawatur that purity is required for fasting. When Quran mentions exceptions for fasting, they are in addition to previously established requirement of purity. Jewish or Christian practice is not a source of deen for us. We can only refer to them in light of Quran and Sunnah.
