COMMENTARY on 79:19
A. Yusuf Ali:

Translation:
"´And that I guide you to your Lord, so you 5930 shouldst fear Him?´"
Commentary:

5930  Even for such a one as Pharaoh, intoxicated with his own power and greatness, guidance and grace were offered through Moses.

 

Muhammad Asad:

Translation:
[If so,] then I shall guide thee towards [a cognition of] thy Sustainer, so that [henceforth] thou wilt stand in awe [of Him].’" 8
Commentary:
