Q: Does one have to intend fasting every day during the month of Ramadan or is
intending once at the beginning of the month sufficient?
A: Assuming one intends, on the night preceding the first day, that one wills to
fast throughout the whole month, this will be deemed sufficient; however, it is
better (mustaḥabb caution) to intend one’s fasting of each day during the
previous night as well.
