The foundation of Islamic law is rooted in ease, universality, and accessibility—not in complexity, technicality, or scientific exclusivity. Islam is a religion meant for all people across cultures, levels of education, and geographies. Its laws are designed to be practical and implementable so that every Muslim can fulfill their religious obligations with clarity and confidence.

This principle of simplicity is reflected in the Prophet Muhammad’s ﷺ guidance on determining the beginning of lunar months, particularly Ramadhan and Eid:

“Fast when you see it (the new moon), and break your fast when you see it. If it is cloudy, then complete Sha‘ban as thirty days.” (Sahih Bukhari; Sahih Muslim)

“We are an unlettered nation; we neither write nor calculate. The month is like this and this,” (showing 29 or 30 days with his fingers) (Sahih Bukhari; Sahih Muslim)

The debate over calculation gained new momentum with the rise of precise astronomical science and the global dispersion of Muslim communities. This issue reflects a deeper dynamic between tradition and modernity, text and science, and the need for both precision and unity. While differing opinions remain—and may continue for the foreseeable future—they all stem from a shared devotion to honoring the sacred times established by Allah. In navigating these differences, it is important that we act with taqwa, approaching the matter with sincerity, humility, and mutual respect, always seeking to preserve the unity and integrity of the Ummah.
