Message 9: The Date Does Not Change at Sunset

The Day Ends When Night Begins This message examines the Qur’anic boundary between day and night through Q 2:187, Q 84:16, and Q 36:37–40. The study argues that the Qur’an begins the fasting day at fajr and requires fasting to continue until layl / night. It does not state that sunset itself is the beginning of night or the automatic boundary of a new date. The author interprets al-shafaq—the rosy dusk—as the evening transition through which the remaining daytime light passes into night. The MESSAGE also presents six supporting mathematical observations concerning fajr, shafaq, layl, the Sun, the Moon, the Qur’an, and the restricted daytime field نهار / النهار. It distinguishes the Qur’anic terms for daytime, day/date, and night, and explains why a later event occurring during twilight cannot retroactively change the date at sunset. This publication is part of the Qur’an Study MESSAGE Series and presents the author’s Qur’an-by-the-Qur’an interpretation. The Arabic Qur’an remains the governing MESSAGE.
