Surah Al-Nahl (The Bees), Verse 85

وَاِذَا رَاَ الَّذِیْنَ ظَلَمُوا الْعَذَابَ فَلَا یُخَفَّفُ عَنْهُمْ وَلَا هُمْ یُنْظَرُوْنَ ۟

Wa izaa ra al lazeena zalamul 'azaaba falaa yukhaf fafu 'anhum wa laa hum yunzaroon

“When the wrong-doers (actually) see the Penalty, then will it in no way be mitigated, nor will they then receive respite.”
