The lunar calendar depends on the sighting of the moon and usually, there is confusion as to whether the moon has been sighted or not. This confusion and anxiety is most palpable at the time of Ramadhan and ‘Eid Ul Fitr. To quell this anxiety, Hadhrat Shaykh Ul Islam (May Allah shower His Mercy on him) founded a committee “Ruyat-e-Hilaal Committee”. He included erudite scholars and astronomers in this committee and would also personally supervise it. This committee is still serving the populace in Hyderabad, Deccan and surrounding areas.
