An-Naba 78:3–5
They disagreed about it
ٱلَّذِى هُمْ فِيهِ مُخْتَلِفُونَ ٣ كَلَّا سَيَعْلَمُونَ ٤ ثُمَّ كَلَّا سَيَعْلَمُونَ ٥
The meaning, simply
The disbelievers of Quraysh disagreed about this news: some doubted it and some called it a lie. Allah tells them: it is not as you claim; on the Day of Resurrection they will know it is true, and then they will know it for certain.

Think with me
Why did Allah repeat "they will know" twice?
