Question
My menstruation started from the 13th of Ramadan to the 23rd of Ramadan, and it was on time. It came again after 5 days, meaning on the 28th of Ramadan, and it has not stopped until now. What is the ruling on this, and is my prayer valid?
Answer
I say, and with God's success: What came in the second instance is considered blood of istihada (irregular bleeding) and not menstruation, and the prayer and fasting during it are valid; because the minimum period of purity between two menstruations is 15 days. And God knows best.
