[Machine] I heard the Messenger of Allah ﷺ say, "Fasting during the month of patience (Ramadan) and three days of every month is equivalent to fasting the whole of one's life, and it removes the impurities of the heart." I asked, "What are the impurities of the heart?" He said, "The whisperings of Satan."
