The Holy Quran 55:5 — Surah Ar-Rahman
Arabic text
ٱلشَّمْسُ وَٱلْقَمَرُ بِحُسْبَانٍ
Translation
(Another of His favours is that) The sun and moon are (travelling) by calculated courses (orbits which Allaah has set for them until their end of time). (Because of these fixed courses, man is able to accurately calculate time so that he can plan and organise his activities.)
Tafsir (excerpt) — Tafsir Usmani
