Surah Al-Ahzab (The Enemy Alliance), Verse 63

یَسْـَٔلُكَ النَّاسُ عَنِ السَّاعَةِ قُلْ اِنَّمَا عِلْمُهَا عِنْدَ اللّٰهِ وَمَا یُدْرِیْكَ لَعَلَّ السَّاعَةَ تَكُوْنُ قَرِیْبًا ۟

Yas'alukan naasu 'anis Saa'ati qul innamaa 'ilmuhaa 'indal laah; wa maa yudreeka la'allas Saa'ata takoonu qareebaa

“Men ask thee concerning the Hour: Say, "The knowledge thereof is with Allah (alone)": and what will make thee understand?- perchance the Hour is nigh!”
