The Saudi Arabia Supreme Court has called all the Muslims across the all Kingdom to sight the crescent moon of the holy month of Ramadan on Friday night, April 1.

After this announcement, the court urged those who were going to watch the moon with the naked eye or through binoculars that they need to report to the nearest court and register their testimonies or report to the nearest center that can contact a court.

Ramadan is the ninth and holiest month of the Islamic or Hijri calendar. It is also considered a month of the Quran revealed to the Prophet Mohammed.

Muslims continuously fast from sunrise to sunset every day of the month, which is typically either 29 or 30 days.

If the moon is observed over the Kingdom on Friday, the holy month will begin the next day. If not, it will start on Sunday.

When it comes to determining the days on which major religious events, such as the start of Ramadan and Eid Al Fitr, which marks the end of the holy month, the Muslim world typically looks to Saudi Arabia.

On Monday, the Kingdom declared restrictions on volume levels for loudspeakers at mosques during Ramadan.

Speakers must not exceed a third of their total volume, the Ministry of Islamic Affairs said.

Officials have asked mosque staff to ensure they abide by circulars that limit the use of external loudspeakers for the first (adhan) and second (iqamah) calls to prayer.

Speakers cannot be used for additional prayers during the holy month.
