هُوَ الَّذِى جَعَلَ الشَّمْسَ ضِيَآءً وَالْقَمَرَ نُوراً وَقَدَّرَهُ مَنَازِلَ لِتَعْلَمُواْ عَدَدَ السِّنِينَ وَالْحِسَابَ مَا خَلَقَ اللَّهُ ذَلِكَ إِلاَّ بِالْحَقِّ يُفَصِّلُ الآيَـتِ لِقَوْمٍ يَعْلَمُونَ - إِنَّ فِى اخْتِلَـفِ الَّيْلِ وَالنَّهَارِ وَمَا خَلَقَ اللَّهُ فِى السَّمَـوَتِ وَالاٌّرْضِ لآيَـتٍ لِّقَوْمٍ يَتَّقُونَ
