Surah 36. Yasin, Ayah 46

Or: "no sign of their Sustainer's signs" - since the noun ayah, repeated several times in the preceding passage, denotes "a message" as well as "a sign".

The Signs of Allah are many, in His great world,-in nature, in the heart of man, and in the Revelation sent through His messengers. They turn away from all of them, as a man who has ruined his eyesight turns away from the light.
