Surah 90. Al-Balad, Ayah 10

The two highways of life are: (1) the steep and difficult path of virtue, which is further described in the verses following, and (2) the easy path of vice, and the rejection of Allah, referred to in verses 19-20 below. Allah has given us not only the faculties implied in the eyes, the tongue, and the lips, but has also given us the judgment by which we can choose our way; and He has sent us Teachers and Guides, with Revelation, to show us the right and difficult way.
