إِنَّ لَدَيْنَآ أَنكَالًا وَجَحِيمًا
Indeed, with Us [for them] are shackles and burning fire
وَطَعَامًا ذَا غُصَّةٍ وَعَذَابًا أَلِيمًا
And food that chokes and a painful punishment -
إِنَّآ أَرْسَلْنَآ إِلَيْكُمْ رَسُولًا شَـٰهِدًا عَلَيْكُمْ كَمَآ أَرْسَلْنَآ إِلَىٰ فِرْعَوْنَ رَسُولًا
Indeed, We have sent to you a Messenger as a witness upon you just as We sent to Pharaoh a messenger.
فَعَصَىٰ فِرْعَوْنُ ٱلرَّسُولَ فَأَخَذْنَـٰهُ أَخْذًا وَبِيلًا
But Pharaoh disobeyed the messenger, so We seized him with a ruinous seizure.
