فَقَدْ كَذَّبُوكُم بِمَا تَقُولُونَ فَمَا تَسْتَطِيعُونَ صَرْفًۭا وَلَا نَصْرًۭا ۚ وَمَن يَظْلِم مِّنكُمْ نُذِقْهُ عَذَابًۭا كَبِيرًۭا
Thus they will give you the lie regarding what ye say, then ye can neither avert (the doom) nor obtain help. And whoso among you doeth wrong, We shall make him taste great torment.
Surah Al-Furqaan(25:19)
