Moon Sighting in Islam: Saudi Method Explained

Many Muslims assume moon sighting is a single, uniform process — it isn't. This article explains how Saudi Arabia determines the start of Ramadan, what that method means for you, and how to plan your worship around differences in sighting.

TL;DR Summary

• Follow official announcements from trusted authorities for your community.
• Saudi relies on combined physical sightings and expert testimony.
• Compare local sighting with Saudi only after checking methodology.
• Use clear prayer and fasting plans that adapt to one-day differences.
• Prepare spiritually early so one-day uncertainty doesn't disrupt worship.
• Consult qualified scholars for personal fiqh questions and disputes.
• Track moon data practically, not obsessively, for community unity.
• Use reliable sources to avoid misinformation and emotional stress.

"يَسْأَلُونَكَ عَنِ الْأَهِلَّةِ قُلْ هِيَ مَوَاقِيتُ لِلنَّاسِ"

"They ask you about the new moons. Say: They are measurements of time for the people."

— Quran 2:189

This short video outlines Saudi Arabia's practical steps for observing the new crescent and announcing Ramadan.

How Saudi Arabia determines the start of Ramadan

Official procedure and witnesses

Saudi Arabia coordinates reports from trained observers and judicial committees. They collect testimony from multiple witnesses, examine reports for consistency, and consult astronomical data to confirm plausibility.

• Saudi committees accept trustworthy eyewitness testimony from multiple regions.
• They cross-check sighting times and consider weather and visibility.
• Astronomical calculations are used as supporting evidence, not the sole proof.

Common mistake Relying solely on social media confirmations can cause confusion; always wait for an official statement from recognized religious authorities.

Role of astronomical data and visibility criteria

Saudi practice uses astronomy to assess whether a physical sighting was possible at the reported location and time. Calculations help filter false reports but do not replace eyewitness testimony in the standard approach.

• Use astronomical data to understand the likelihood of sighting.
• Treat calculations as corroboration, not the final ruling unless the authority declares otherwise.
• The visible crescent (hilal) and local weather are decisive for eyewitness credibility.

How this affects Muslims in other countries

If Saudi announces Ramadan, some communities follow Saudi while others follow local sighting. The choice often depends on jurisprudential positions and historic practice in that country.

• Compare local mosque guidance with Saudi announcements.
• Choose a consistent authority to follow to avoid personal confusion.
• When communities differ, prioritize communal worship unity.

According to Islamic scholars, aligning with a trusted authority preserves communal cohesion and worship effectiveness. (See related discussion on moon-sighting criteria and practice: https://www.islamicity.org/1194/moon-sighting-criteria/)

Practical steps you can take in the week before Ramadan

Check reliable announcements and sources

Monitor official religious councils, mosques, and trustworthy news. Avoid unverified social posts.

• Follow your mosque's official channels.
• Check national Islamic authority statements early evening.
• Use authoritative online resources for context.

Prepare a one-day contingency plan

Accept that Ramadan may shift by one day; plan your meals, work, and worship so a one-day change is manageable.

• Prepare suhoor-friendly grocery items for both possibilities.
• Notify family and colleagues about possible changes to schedules.
• Keep your worship routine adaptable.

Spiritual focus in the final week

Fix small, repeatable acts to preserve momentum when the month begins.

• Increase Qur'an recitation by specific pages per day.
• Plan short nightly prayers and duʿā lists.
• Set charity targets to start immediately.

For fiqh implications about following different sightings, see guidance from established hadith collections and juristic discussions (general references: https://sunnah.com/bukhari:1).

• Verify local mosque announcement
• Prepare suhoor supplies for two possible start dates
• Set Qur'an and prayer goals for first ten days
• Confirm work or school notifications if required

Tip If visibility is uncertain, prioritize small, consistent acts of worship so the first day begins with momentum regardless of the exact date.

Common questions about physical sighting vs calculations

When do scholars accept calculations?

Some contemporary scholars accept calculations for astronomical certainty, especially when visibility is impossible due to location or extreme weather. Others maintain that physical sighting fulfills the prophetic practice (the sunnah of the Prophet ﷺ).

• Calculations gain acceptance where eyewitnessing is impractical.
• Physical sighting remains the traditional default for many jurists.
• Consult a local scholar to know which approach applies in your situation.

If Saudi confirms, should I fast if my local mosque doesn't?

If Saudi announces Ramadan but your community hasn't accepted that ruling, prioritize the decision of your local, legitimate authority to maintain communal unity in prayer and fasting. If you're certain your local community will follow Saudi, align with their announcement.

Reconciling differing opinions with family

Discuss the matter calmly, explain the chosen authority, and agree on a shared plan for community prayers and family meals to avoid division.

Conclusion

Saudi Arabia combines trustworthy eyewitness testimony with astronomical checks to confirm the new crescent before announcing Ramadan. That method prioritizes physical sighting backed by expert verification, which some communities adopt directly while others prefer local sighting or calculated calendars. You can reduce confusion by choosing one reputable authority to follow, preparing a simple one-day contingency plan, and building consistent spiritual habits well before the month begins. When in doubt about rulings, consult a qualified scholar and prioritize communal unity where possible. May your planning bring ease, unity, and focused worship when the Ramadan moon arrives.
