The desire to have more of the worldly gains have pre-occupied you so much (that you have neglected remembring God)
until you come to the graves
You shall know
You shall cetainly know (about the consequences of your deeds)
You will certainly have the knowledge of your deeds beyond all doubt
You will be shown hel
and you will see it with your own eyes
Then, on that day, you will be questioned about the bounties (of God)
