Verse 10

أَعَدَّ ٱللَّهُ لَهُمْ عَذَابًا شَدِيدًا فَٱتَّقُوا۟ ٱللَّهَ يَـٰٓأُو۟لِى ٱلْأَلْبَـٰبِ ٱلَّذِينَ ءَامَنُوا۟ قَدْ أَنزَلَ ٱللَّهُ إِلَيْكُمْ ذِكْرًا

God has promised them an ultimate suffering, therefore fear God, O you who possess vision, and have attained faith. God has indeed revealed to you a reminder.
