Surah Al-Ahqaf (The Sand-Hills), Verse 23

قَالَ اِنَّمَا الْعِلْمُ عِنْدَ اللّٰهِ وَاُبَلِّغُكُمْ مَّاۤ اُرْسِلْتُ بِهٖ وَلٰكِنِّیْۤ اَرٰىكُمْ قَوْمًا تَجْهَلُوْنَ ۟

Qaala innamal 'ilmu indal laahi wa uballighukum maaa ursiltu bihee wa laakinneee araakum qawman tajhaloon

“He said: "The Knowledge (of when it will come) is only with Allah: I proclaim to you the mission on which I have been sent: But I see that ye are a people in ignorance!"..”
