Surah 16. An-Nahl, Ayah 11

The least thought and study of nature will show you Allah's wise and benign Providence in making the processes of nature subserve man's use and refined life. A higher degree of intelligence and study is required ("men who are wise") to understand Allah's Signs to man in the processes connected with the heavenly bodies (verse 12). And a still higher spiritual understanding ("men who celebrate His praises" with gratitude) to realise the marvellous gradations, colours, and nuances in the creatures on this little globe of ours (verse 13), Reason this out carefully.
