السلام عليكم ورحمة الله وبركاته احسن الله اليك Would it be correct to say all believers are smart and all kuffaar are not smart by default regardless of their IQ and these things because the disbeliever has been scammed by paying the price of the next life over this life?

Ustadh AbdulAziz al-Haqqan

In dunya matters they can he smart or in a certain field for example, as for the hereafter it is different their cleverness did not serve them well.
