Al-Furqan 25:19

Faqad kaththabookum bimataqooloona fama tastateeAAoona sarfan walanasran waman yathlim minkum nuthiqhuAAathaban kabeera

So they will deny you, [disbelievers], in what you say, and you cannot avert [punishment] or [find] help. And whoever commits injustice among you - We will make him taste a great punishment.

Thus they will refute you in what you say, and you will not be able to repulse (the punishment,) or to receive help. Whoever commits injustice from among you, We will make him taste a painful punishment.
