THE HOURS DECREED FOR FASTING

According to the Qur’an, the fasting hours are as follows: You can eat and drink until you can discern the white streak (of dawn) against the black streak (of night); then complete the Fast until night sets in (2:187). Thus, the fast should start at the first thread of light at dawn (between 1.5 and 2 hours before sunrise, depending on the time of year), and maintained until sunset (the beginning of night).
