day Muslim World League conference on lunar months and astronomical calculations began here Saturday. The conference is being attended by Sheikh Abdul Aziz Aal Al-Sheikh, Grand Mufti of the Kingdom, Sheikh Abdullah Bin Abdul Mohsin Al-Turki, Secretary General of MWL, Sheikh Saleh Bin Abdul Aziz Aal Al-Sheikh, Minister of Islamic Affairs, Call and Guidance, and scholars of other Muslim countries. Al-Turki said the meeting had been called to deliberate on the issue of astronomical calculations. Scholars discussed if calculations could be used to unite the Muslim Ummah in determining the fast of Ramadan, Haj and the two Eids. The Grand Mufti said that Islam had defined that the beginning and ending of the fast depends on the sighting of the crescent, and that the Muslim Ummah has always followed this. Former Justice of the Supreme Court of Pakistan, Taqi Osmani, said the meeting was being held to end differences and unite the Ummah under one banner. __
