Sir: Moon sighting was not as divisive hundreds of years ago as it is today. In the past, Muslim scholars agreed on a certain method to decide the start and end of the month of Ramazan. But with significant advancements in technology in the past few years, these divisions have widened in some regions of the world. The government is well aware of the controversy surrounding separate moon sightings in the country. Observers feel that unless a law is passed to bring everyone on the same page and promote unity and harmony in such matters, separate moon-sightings will continue to be an issue in the future, again the dispute being raised.
