But now our Sustainer's word has come true against us [as well]: verily, we are bound to taste [the fruit of our sins].

"So now has been proved true, against us, the word of our Lord that we shall indeed (have to) taste (the punishment of our sins).

Now the Word of our Lord hath been fulfilled concerning us. Lo! we are about to taste (the doom).

So the word of our Lord has proved true against us: we shall surely taste.

So the word of our Lord has come into effect upon us; indeed, we will taste [punishment].
