20:129
وَلَوْلَا كَلِمَةٌ سَبَقَتْ مِن رَّبِّكَ لَكَانَ لِزَامًا وَأَجَلٌ مُّسَمًّى
walawlā kalimatun sabaqat min rabbika lakāna lizāman wa-ajalun musamman
If it were not for a preordained Word from your Lord [Prophet], they would already have been destroyed. Their time has been set,
And had it not been for a Word that went forth before from your Lord, and a term determined, (their punishment) must necessarily have come (in this world).
