This verse speaks to the core theme of **Ar-Ra'd**.
Reflect on the meaning: "To Him alone is the supplication of truth. And those they call upon besides Him do not respond to them with a thing, except as one who stretches his hands toward water from afar, calling it to reach his mouth, but it will not reach it thus. And the supplication of the disbelievers is not but in error i.e., futility.".
