"Indeed, in the creation of the heavens and the earth and the alternation of the night and the day are signs for those of understanding" [meaning: those possessed of intellect]; and they are the believers.
﴿إِن فِي خلق السَّمَاوَات وَالأَرْضِ وَاخْتِلافِ اللَّيْلِ وَالنَّهَارِ لآيَاتٍ لأولي الْأَلْبَاب﴾ [يَعْنِي: أولي الْعُقُول]؛ وهم الْمُؤْمِنُونَ.
