And yet, they [who deny the truth] are wont to ask, "When is that promise [of resurrection and judgment] to be fulfilled? [Answer this, O you who believe in it,] if you are men of truth!"

They say: "When will this promise come to pass,- if ye speak the truth?"

And they say: When will this promise be fulfilled, if ye are truthful?

And they say: When will this promise be fulfilled, if you are truthful?

And they say, "When is [the fulfillment of] this promise, if you should be truthful?"
