هُوَ الَّذِي جَعَلَ الشَّمْسَ ضِيَاءً وَالْقَمَرَ نُورًا وَقَدَّرَهُ مَنَازِلَ لِتَعْلَمُوا عَدَدَ السِّنِينَ وَالْحِسَابَ مَا خَلَقَ اللَّهُ ذَلِكَ إِلا بِالْحَقِّ يُفَصِّلُ الآيَاتِ لِقَوْمٍ يَعْلَمُونَ
In this context, the sun seems to represent a shining light in society contrasted with the moon. Allah is said to measure their descent, perhaps showing their placement in social dimensions. This descent will help us to understand the preparation of the sineen (pathways in society) and the calculation. This creation is said to be with truth (thus deconstructible with al-haqq) and this is a detailing of signs for those who are continuously in the know.
