Al-Kahf 18:7
إِنَّا جَعَلْنَا مَا عَلَى ٱلْأَرْضِ زِينَةً لَّهَا لِنَبْلُوَهُمْ أَيُّهُمْ أَحْسَنُ عَمَلًا
Inna jaAAalna ma AAalaal-ardi zeenatan laha linabluwahum ayyuhum ahsanuAAamala
Indeed, We have made that which is on the earth adornment for it that We may test them [as to] which of them is best in deed.
Surely, We have made what is on earth an adornment for it, so that We test them as to who among them is better in deeds.
