Surah Al-Nahl (The Bees), Verse 38

وَاَقْسَمُوْا بِاللّٰهِ جَهْدَ اَیْمَانِهِمْ لَا یَبْعَثُ اللّٰهُ مَنْ یَّمُوْتُ بَلٰی وَعْدًا عَلَیْهِ حَقًّا وَّلٰكِنَّ اَكْثَرَ النَّاسِ لَا یَعْلَمُوْنَ ۟

Wa aqsamoo billaahi jahda aimaanihim laa yab'asul laahu mai yamoot; balaa wa'dan 'alaihi haqqanw wa laakinna aksaran naasi laa ya'lamoon

“They swear their strongest oaths by Allah, that Allah will not raise up those who die: Nay, but it is a promise (binding) on Him in truth: but most among mankind realise it not.”

Quran 16:38 (Yusuf Ali Translation)
