33.19 . Being sparing of their help to you ( believers ) . But when the fear cometh , then thou ( Muhammad ) seest them regarding thee with rolling eyes like one who fainteth unto death . Then , when the fear departeth , they scald you with sharp tongues in their greed for wealth ( from the spoil ) . Such have not believed . Therefor Allah maketh their deeds fruitless . And that is easy for Allah .
