Question
A girl performs prayer and fasting during her menstrual period because she believes there is no legal evidence prohibiting this. What is the ruling on her action?
Answer
I say, and with God's help: This issue has consensus without disagreement among the imams of Islam throughout history, and whoever does it commits a major sin and a great wrongdoing. Piety is not measured by the abundance of worship, but by adherence to the limits of the Sharia. And God knows best.
