For the infidels it is not easy.
For the disbelievers, not easy.
and it will not be easy for the unbelievers
For the disbelievers, anything but easy
On the disbelievers (it is)not easy
A hard Day for the disbelievers
Not easy upon the disbelievers
For the disbelievers it will not be easy
Not at all easy for the disbelievers
For the disbelievers it will not be easy (to behold the complete triumph of Truth)
Far from easy for the disbelievers
