What you have been promised (and warned of, concerning your future and the Hereafter), is indeed bound to happen, and you have no power at all to frustrate it
Indeed, what you are promised is coming... You cannot cause Allah failure (to deliver His promise)!
Sayyed Abbas Sadr-Ameli
Verily what you are promised, will certainly come, and you cannot make (Allah) helpless (to flee from His retribution)
Al-muntakhab fi tafsir al-Qur'an al-Karim
You people had better realize that all that you have been promised shall come to pass at the predetermined point of time and you shall not be able to avert what shall befall you nor things threatened
