﴿ إِنَّا جَعَلْنَا مَا عَلَى ٱلْأَرْضِ زِينَةًۭ لَّهَا لِنَبْلُوَهُمْ أَيُّهُمْ أَحْسَنُ عَمَلًۭا ﴾

“Behold, We have willed that all beauty on earth be a means by which We put men to a test, [showing] which of them are best in conduct;”

Truly We have made all that is on the earth in the way of animals plants trees rivers and so on as an adornment for it that We may try them that We may test mankind observing thereby which of them is best in conduct therein that is to see which of them is the most abstemious of it.
