Surah Al-Kahf — Ayah 7 (18:7)
إِنَّا جَعَلۡنَا مَا عَلَى ٱلۡأَرۡضِ زِينَةٗ لَّهَا لِنَبۡلُوَهُمۡ أَيُّهُمۡ أَحۡسَنُ عَمَلٗا ٧
English translation (Saheeh International)
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.
Brief commentary
Surely, I have made the creation on the face of this earth an adornment for it, so I can test them to see which of them does the best actions which please Allah and which of them is worst in actions, so that I may reward everyone with what they deserve.
