(An-Naba') 78 : 5
ثُمَّ كَلَّا سَيَعْلَمُونَ
Again, nay; surely, very soon they will come to know.
This teaches that whatever the Three-Time Knowledge—Adhikr—predicts will surely come to pass without any difference. It is told in 17: 107-109: “You believe with It or do not believe; indeed, those who were given the Knowledge before It—when It is explained to them—they fall upon their faces in prostration. And they say: ‘Glory is to our Lord! Indeed, the Promise of our Lord will be fulfilled.’ And they fall upon their faces weeping, and It increases them in humble submission.”
