Question
I intended to fast a missed fast and woke up to the call to prayer at dawn, thinking it was the first call, so I drank water and intended to fast. Then I discovered it was the second call. Should I continue fasting and refrain for the rest of the day or not?
Answer
I say, and with God's success: The fast is invalidated due to this mistake, and it is permissible to eat afterwards, and to fast on another day, and God knows best.
