Celebrating Eid is some time disputed among the different sects of Muslims. The Muslim world never or rarely celebrated an Eid on the same day. Starting the month of Ramadan is another issue among the Muslim brotherhood. Every year Muslims around the world eagerly await news of the moon sighting as the Prophet Muhammed (saw) said,
“Fast when the moon is sighted and stop fasting when the moon is sighted...otherwise complete thirty days..”
On the face of it this sounds straight forward. Everyone looks for the moon and if no one sees it we complete thirty days of Sha’ban and fast on the next; a lunar month is never more than thirty days.
Can Eid be celebrated on the same day around the world ? watch Dr Zakir Naik views about this question.
