The Holy Quran, Surat An-Nabaa - النبأ

إِنَّا أَنذَرْنَاكُمْ عَذَاباً قَرِيباً يَوْمَ يَنظُرُ الْمَرْءُ مَا قَدَّمَتْ يَدَاهُ وَيَقُولُ الْكَافِرُ يَا لَيْتَنِي كُنتُ تُرَاباً

Lo! We warn you of a doom at hand, a day whereon a man will look on that which his own hands have sent before, and the disbeliever will cry: "Would that I were dust!"
