إِنَّ مَا تُوعَدُونَ لَآتٍ وَمَا أَنتُم بِمُعْجِزِينَ
Indeed what you are promised will surely come, and you will not be able to thwart it.
Agha Ali Puya Commentary
Commentary on Quran 6:134
[Pooya/Ali Commentary 6:134] Tu-aduna literally means "promised", but here it implies the warning of punishment to be inflicted upon the disbelievers on the day of judgement.
