COMMENTARY on 90:9
A. Yusuf Ali:

Translation:
And a tongue, 6137 and a pair of lips?-
Commentary:

6137  The eyes give us the faculty of seeing, and may be taken in both the literal and the metaphorical sense. In the same way the tongue gives us the faculty of tasting in both senses. Along with the lips, it also enables us to speak, to ask for information and seek guidance, and to celebrate the praises of Allah.

 

Muhammad Asad:

Translation:
and a tongue, and a pair of lips, 6
Commentary:
6  I.e., to recognize and to voice the truth of God's existence or, at least to ask for guidance.
