Q. What is the position of the Muslims in Utah regarding the moon sighting? Do your feel that we must become scientific and follow calculations? Or do your feel the sunnah method is the best?
A. Since the issue pertains to religion, al-Islam, it would be best to follow the sunnah method regarding issues that pertain to the moon. Calculations should be used by scholars with the help of the scientific community so as to determine if people are false in their claims of having sighted the moon.
Allah Certainly Knows Best.
