مريم — Maryam Ayat 39
وَاَنْذِرْهُمْ يَوْمَ الْحَسْرَةِ اِذْ قُضِيَ الْاَمْرُۘ وَهُمْ فِيْ غَفْلَةٍ وَّهُمْ لَا يُؤْمِنُوْنَ
Wa anżirhum yaumal-ḥasrati iż quḍiyal-amr(u), wa hum fī gaflatiw wa hum lā yu'minūn(a).
"And warn them, [O Muhammad], of the Day of Regret, when the matter will be concluded; and [yet], they are in [a state of] heedlessness, and they do not believe."
