Sūrah Aṭ-Ṭāriq The Nightly Star
الطارق
Al-Qurṭubī derives from this surah's nighttime star imagery the fiqh ruling on hilāl (new moon) sighting for establishing Ramaḍān the number of witnesses required and the school positions.
Al-Qurṭubī derives from this surah's oath by the nightly star (aṭ-ṭāriq) and the Qurʾān's repeated celestial imagery the legal framework for Islamic calendar determination based on celestial observation. The prophetic instruction "fast when you see it [the new moon] and break the fast when you see it" grounds the legal debate on how many witnesses are needed to validate the new moon sighting for Ramaḍān.
The majority (Ḥanafī, Shāfiʿī, Ḥanbalī) accept one reliable Muslim witness for the beginning of Ramaḍān, based on the prophetic acceptance of Ibn ʿUmar's single witness account. The Mālikī school requires two witnesses for the beginning (treating it as a legal matter requiring the standard two-witness evidentiary threshold). For the ending of Ramaḍān (establishing Shawwāl), all schools require two witnesses the obligation of fasting continues until clearly established otherwise, and the stricter standard applies.
- Beginning of Ramaḍān: one reliable witness (Ḥanafī, Shāfiʿī, Ḥanbalī); two witnesses (Mālikī) the most significant practical disagreement in Islamic calendar determination.
- End of Ramaḍān (beginning of Shawwāl): two witnesses required by all schools the stricter standard applies because fasting obligation continues unless clearly established otherwise.
- The prophetic method (ru'yat al-hilāl physical moon sighting) is the established Islamic method; modern astronomical calculation is a supplement discussed by contemporary scholars.
- The witness must be a reliable (ʿadl) Muslim character verification (tazkiyah) of the witness is required before accepting the testimony.
- Local vs. global sighting: the schools differ on whether a moon sighting in one location is binding for all Muslims majority hold it applies locally; minority hold it applies universally once established.
