فَلَنُذِيقَنَّ ٱلَّذِينَ كَفَرُوا۟ عَذَابًا شَدِيدًا وَلَنَجْزِيَنَّهُمْ أَسْوَأَ ٱلَّذِى كَانُوا۟ يَعْمَلُونَ
Falanuzeeqannal lazeena kafaroo 'azaaban shadeedanw wa lanajziyannahum aswallazee kaanoo ya'maloon
We shall certainly give the disbelievers a taste of severe punishment. We shall repay them according to their worst deeds-
So we will surely make those who deny taste a severe punishment, and we will surely repay them for the worst of what they used to do.
