Surah Al A'raf Tafseer

وَإِن تَدْعُوهُمْ إِلَى الْهُدَى لَا يَسْمَعُواْ إِن تَدْعُوهُمْ لَا يَسْمَعُواْ دُعَأءَكُمْ وَتَرَاهُمْ يَنظُرُونَ إِلَيْكَ وَهُمْ لَا يُبْصِرُونَ

and you will see them looking at you, yet they see not.

meaning, they have eyes that stare as if they see, although they are solid. Therefore, the Ayah treated them as if they had a mind (saying, Tarahum, instead of Taraha), since they are made in the shape of humans with eyes drawn on them
