quran:22:7 –

And ˹that they may know˺ that the Hour is coming - no doubt about it - and that Allah will resurrect those in the graves.  

and because the Hour will come, whereof there is no doubt, uncertainty; and because God will resurrect those who are in the graves.
القرآن:٢٢:٧ –

وَأَنَّ السَّاعَةَ آتِيَةٌ لَا رَيْبَ فِيهَا وَأَنَّ اللَّهَ يَبْعَثُ مَنْ فِي الْقُبُورِ  

{وأن الساعة آتية لا ريب} شك {فيها وأن الله يبعث من في القبور} ونزل في أبي جهل.
