A. Yusuf Ali:Translation:
"For you do worship idols besides Allah, and you invent
falsehood. The things that you worship besides Allah
have no power to give you sustenance: then seek you
sustenance 3439 from Allah, serve Him, and be
grateful to Him: to Him will be your return.

Muhammad Asad:Translation:
You worship only [lifeless] idols instead of God, and [thus] you give visible shape to a lie! 13 Behold, those [things and beings] that you worship instead of God have it not in their power to provide sustenance for you: seek, then, all [your] sustenance from God, and worship Him [alone] and be grateful to Him: [for] unto Him you shall be brought back!
3439 Sustenance: in the symbolic as well as the literal sense. Seek from Allah all that is necessary for your upkeep and development, and for preparing you for your future Destiny. Lay all your hopes in Him and in no one else. Dedicate yourselves to His worship. He will give you all that is necessary for your growth and well being, and you should show your gratitude to Him by conforming your will entirely to His ( Cf. n. 3412).
