Surah 76. Al-Insan, Ayah 3

I.e., God has not only endowed man with "hearing and sight", i.e., with reason and the instinctive ability to discern between right and wrong, good and evil (cf. 90:10 ), but He also actively guides him by means of the revelation bestowed on the prophets.

Besides the gift of the faculties, Man has been shown the Way by means of Revelation, through men of the highest spiritual standing. If he is grateful, he will accept Guidance, be of the Righteous, and join the company of the Blessed. If not, he puts chains round himself, thus burdening himself with sin, and gets into the Blazing Fire of Punishment. See next verse. His choice rests on his will.
