And they used to say, "When we die and become dust and bones, are we indeed to be resurrected?

أَوَآبَاؤُنَا الْأَوَّلُونَ

And our forefathers [as well]?"

قُلْ إِنَّ الْأَوَّلِينَ وَالْآخِرِينَ

Say, [O Muhammad], "Indeed, the former and the later peoples

ثُمَّ إِنَّكُمْ أَيُّهَا الضَّالُّونَ الْمُكَذِّبُونَ

Then indeed you, O those astray [who are] deniers,

لَآكِلُونَ مِن شَجَرٍ مِّن زَقُّومٍ

Will be eating from trees of zaqqum

فَمَالِئُونَ مِنْهَا الْبُطُونَ

And filling with it your bellies
