[17:85] And they ask you about the soul. Say: The soul is one of the commands of my Lord, and you are not given aught of knowledge but a little.

[91:1] I swear by the sun and its brilliance,

[91:2] And the moon when it follows the sun,

[91:3] And the day when it shows it,

[91:4] And the night when it draws a veil over it,

[91:5] And the heaven and Him (Allah) Who made it,

[91:6] And the earth and Him Who extended it,

[91:7] And the soul and Him Who made it perfect,

[91:8] Then He inspired it (soul) to understand what is right and wrong for it;

[91:9] He will indeed be successful who purifies it (soul),

[91:10] And he will indeed fail who corrupts it.
