signs
قُلِ انظُرُوا مَاذَا فِي السَّمَاوَاتِ وَالْأَرْضِ وَمَا تُغْنِي الْآيَاتُ وَالنُّذُرُ عَن قَوْمٍ لَّا يُؤْمِنُونَ
Say, “Look at what there is in the heavens and on earth.” Yet neither signs nor warners are of any benefit to those who refuse to believe.
— Quran 10:101
قُلْ سِيرُوا فِي الْأَرْضِ فَانظُرُوا كَيْفَ بَدَأَ الْخَلْقَ
Say: “Travel in the land and see how Allah originated the creation.”
— Quran 29:20
وَفِي الْأَرْضِ آيَاتٌ لِّلْمُوقِنِينَ وَفِي أَنفُسِكُمْ أَفَلَا تُبْصِرُونَ
There are signs on earth for those with sure faith, and also in your own selves. Do you not see?
— Quran 51:20–21
