"Say: Behold what is in the heavens," from its sun, its moon, and its stars, and the wonders contained therein, "and the earth," from its seas, its trees, and its mountains; for in these are great signs and proofs. "But neither signs nor warnings avail a people who do not believe," if they do not accept them and reflect upon them.
﴿قل انْظُرُوا مَاذَا فِي السَّمَاوَات﴾ مِنْ شَمْسِهَا وَقَمَرِهَا وَنُجُومِهَا، وَمَا فِيهَا من الْعَجَائِب ﴿وَالْأَرْض﴾ مِنْ بِحَارِهَا وَشَجَرِهَا وَجِبَالِهَا؛ فَفِي هَذِهِ آياتٌ وَحُجَجٌ عِظَامٌ ﴿وَمَا تُغْنِي الآيَاتُ وَالنُّذُرُ عَنْ قَوْمٍ لَا يُؤمنُونَ﴾ إِذَا لمْ يَقْبَلُوهَا، وَيَتَفَكَّرُوا فِيهَا.
