A. Yusuf Ali:Translation:
Is not Allah enough 4296 for his Servant? But they
try to frighten you with other (gods) besides Him! for
such as Allah leaves to stray, there can be no guide.

Muhammad Asad:Translation:
IS NOT God enough for His servant? And yet, they would frighten thee with those [imaginary divine powers which they worship] beside Him! 39 But he whom God lets go astray can never find any guide,
4296 The righteous man will find Allah enough for all the protection he needs, all the rest and peace he craves for, and all the happiness he can imagine. If the evil ones wish to frighten him with false gods, he knows that that is mere superstition. In the case of idols to whom worship is paid, this is easily intelligible. But there are other false gods which men worship—wealth, power, science, selfish desire, and so on. The idea may occur to them: "this is the right course, but what will men say?" or "shall I lose my case if I tell the truth?" or "will it ruin my chances if I denounce sin in high places?" All such false gods will only mislead and leave their victims in the lurch. The worship of them will lose them the Grace of Allah, which wants to guide and comfort all who seek Allah.
