هُوَ ٱلَّذِى جَعَلَ ٱلشَّمۡسَ ضِيَآءً وَٱلۡقَمَرَ نُورًا وَقَدَّرَهُۥ مَنَازِلَ لِتَعۡلَمُواْ عَدَدَ ٱلسِّنِينَ وَٱلۡحِسَابَ ۚ مَا خَلَقَ ٱللَّهُ ذَٰلِكَ إِلَّا بِٱلۡحَقِّ ۚ يُفَصِّلُ ٱلۡءَايَٰتِ لِقَوۡمٍ يَعۡلَمُونَ
It is He Who made the sun to be a shining glory and the moon to be a light (of beauty), and measured out stages for her; that ye might know the number of years and the count (of time). Nowise did Allah create this but in truth and righteousness. (Thus) doth He explain His Signs in detail, for those who understand.<br/>
He it is Who made the sun a radiance, that is, emitting light, and the moon a light, and determined it, with respect to its movement, in stations: 28 stations in 28 nights every month, becoming concealed for two nights when a particular month has 30 days, or [concealed] for one night, when it has 29 days, so that you might know, thereby, the number of the years and the reckoning. God did not create that, which is mentioned, save in truth, not in vain, exalted be He above such things. He details (read yufassilu or nufassilu, 'We detail') the signs for a people who know, who reflect.
