Surah Maryam (Mary), Verse 39

وَاَنْذِرْهُمْ یَوْمَ الْحَسْرَةِ اِذْ قُضِیَ الْاَمْرُ وَهُمْ فِیْ غَفْلَةٍ وَّهُمْ لَا یُؤْمِنُوْنَ ۟

Wa anzirhum Yawmal hasrati iz qudiyal amr; wa hum fee ghaflatinw wa hum laa yu'minoon

“But warn them of the Day of Distress, when the matter will be determined: for (behold,) they are negligent and they do not believe!”
