20:129

وَلَوْلَا كَلِمَةٌ سَبَقَتْ مِن رَّبِّكَ لَكَانَ لِزَامًا وَأَجَلٌ مُّسَمًّى

Transliteration:

Walawla kalimatun sabaqat min rabbika lakana lizaman waajalun musamman

Word by Word:

And if not (for) a Word (that) preceded from your Lord, surely (would) have been an obligation and a term determined.

Translations:

Now were it not for a decree that has already gone forth from thy Sustainer, setting a term [for each sinner's repentance], it would inescapably follow [that all who sin must be doomed at once].

Had it not been for a Word that went forth before from thy Lord, (their punishment) must necessarily have come; but there is a Term appointed (for respite).

And but for a decree that had already gone forth from thy Lord, and a term already fixed, the judgment would have been inevitable (in this world).

And had not a word gone forth from thy Lord, and a term been fixed, it would surely have overtaken them.

And if not for a word that preceded from your Lord, punishment would have been an obligation [due immediately], and [if not for] a specified term [decreed].
