Key Takeaways
- Surah Al-Isra (17:78) outlines the key solar transitions demarcating Dhuhr, Asr, Maghrib, Isha, and Fajr.
- Complementary verses across Surah Hud, Ta-Ha, and Ar-Rum reinforce the five cosmic intervals of daily remembrance.
- Angel Jibril (peace be upon him) demonstrated the precise start and end boundaries for each prayer to Prophet Muhammad (peace be upon him).
- Modern GPS technology, such as the ad-free Imantree app, accurately converts these celestial sun positions into precise local prayer schedules.
01The Quranic Foundation of Daily Prayer Times
A common question among Muslims and seekers of knowledge is where the five daily prayers are located in the Holy Quran. Allah states in Surah Al-Isra: 'Establish prayer at the decline of the sun until the darkness of the night and [also] the Quran of dawn. Indeed, the recitation of dawn is ever witnessed' (Quran 17:78). Classical mufassirun (exegetes) explain that 'duluk ash-shams' (the decline of the sun from its meridian zenith) encompasses the commencement of Dhuhr and extends into Asr. Meanwhile, 'ghasaq al-layl' (the settling darkness of the night) covers the windows of Maghrib and Isha, and 'qur'an al-fajr' directly designates the Fajr prayer with its extended recitation.
Other passages illuminate these divine appointments with poetic harmony. In Surah Hud (11:114), believers are commanded to establish prayer at 'the two ends of the day and at the approach of the night', delineating morning, late afternoon, and evening. In Surah Ar-Rum (30:17-18), praise is ordained 'when you reach the evening and when you reach the morning... and at nightfall and when you are at midday', explicitly underscoring all five periods in which the universe glorifies its Creator.
02Prophetic Demonstration: The Sunnah and Solar Calculations
While the Quran sets forth the broad cosmic windows, the Prophet Muhammad (peace be upon him) provided the exact boundaries through divine guidance. In an authentic narration recorded in Sunan an-Nasa'i and Jami at-Tirmidhi, Angel Jibril (Gabriel) descended to lead the Prophet (peace be upon him) in prayer across two consecutive days. On the first day, he prayed at the very earliest start of each prayer time; on the second day, he prayed at the very end of each period, concluding: 'The time for prayer is between these two limits.'
These boundaries correspond to visible solar markers: the true dawn (al-fajr as-sadiq) for Fajr, the sun passing its midday zenith (zawal) for Dhuhr, the lengthening of an object's shadow for Asr, the complete dipping of the solar disk below the horizon for Maghrib, and the disappearance of the twilight glow (shafaq) for Isha. Historically observed with astrolabes and gnomons, these calculations honour the magnificent order embedded in Allah's creation.

Frequently Asked Questions
Does the Quran explicitly name all five prayers by name?
The Quran explicitly names three prayers directly by name: Salat al-Fajr and Salat al-Isha in Surah An-Nur (24:58), and Salat al-Wusta (the Middle Prayer, traditionally identified as Asr) in Surah Al-Baqarah (2:238). The full five times are described through solar positions in Surah Al-Isra (17:78) and Surah Ar-Rum (30:17-18).
Why do prayer times change slightly every day?
Because Islamic prayer times are based on the earth's rotation and orbit around the sun, the angles of the sun relative to any given location on earth shift day by day. Modern calculation methods apply spherical trigonometry to astronomical data to determine exact prayer minutes.
