Question: During Ramadaan, I woke up 7 minutes after Fajr (Dawn) Athaan (call to Prayer) to drink, and I did not know whether the Athaan had been made. A friend told me not to drink until we became sure whether the dawn had broken. However, I drank, and afterwards he informed me that Fajr Athaan had been called 7 minutes before. Knowing that I fasted the entire day, is it obligatory on me to offer Kaffaarah (expiation) and make up for that day? What is the ruling?
