It determines the beginning and end of Islamic lunar months, including major occasions like Ramadan, Eid al-Fitr, and Eid al-Adha.

The Importance of Moon Sighting in Islam
Islam follows the Hijri (lunar) calendar, where months are based on the phases of the moon. Unlike the solar calendar, the lunar calendar is shorter, consisting of 354 or 355 days. Thus, key religious events are not fixed to specific Gregorian dates but shift each year.
Why is Moon Sighting Essential?
-
To confirm the start and end of Ramadan.
-
To determine the days of Eid al-Fitr and Eid al-Adha.
-
To mark sacred months like Muharram and Dhul-Hijjah.
-
To maintain unity within the Ummah by adhering to the Sunnah.
Moon Sighting in the Quran
Surah Al-Baqarah (2:189)
“They ask you about the new moons. Say, ‘They are measurements of time for the people and for Hajj.'”
[Surah Al-Baqarah: 189]
This verse highlights that the phases of the moon serve as a calendar for Muslims to organize religious duties, including fasting and pilgrimage.
Surah Yunus (10:5)
“It is He who made the sun a shining light and the moon a derived light and determined for it phases – that you may know the number of years and account [of time].”
[Surah Yunus: 5]
The Quran directly mentions that Allah has created the phases of the moon to help humanity reckon with time.
Moon Sighting in Hadith
Hadith #1 – Start Ramadan by Sighting the Moon
The Prophet Muhammad (PBUH) said:
“Fast when you see it (the new moon) and break your fast when you see it, and if it is obscured to you, then complete the number (of Sha’ban) as thirty days.”
[Al-Bukhari, Hadith No. 1909 | Muslim, Hadith No. 1081]
Hadith #2 – Testimony of One Person is Sufficient for Ramadan
“The people looked for the moon, so I informed the Prophet that I had seen it. He fasted and ordered the people to fast.”
[Abu Dawood | Sahih]
This Hadith confirms that even the testimony of one trustworthy person is accepted for starting Ramadan.
Methods of Moon Sighting
Traditional Method

Naked eye observation: The most authentic and recommended method according to Sunnah.

Using optical aids: While not explicitly mentioned, some scholars allow the use of binoculars to assist the sighting.
