Surah Muhammad (Muhammad), Verse 18

فَهَلْ یَنْظُرُوْنَ اِلَّا السَّاعَةَ اَنْ تَاْتِیَهُمْ بَغْتَةً فَقَدْ جَآءَ اَشْرَاطُهَا فَاَنّٰی لَهُمْ اِذَا جَآءَتْهُمْ ذِكْرٰىهُمْ ۟

Fahal yanzuroona illas Saa'ata an ta'tiyahum baghtatan faqad jaaa'a ashraatuhaa; fa annaa lahum izaa jaaa'at hum zikraahum

“Do they then only wait for the Hour,- that it should come on them of a sudden? But already have come some tokens thereof, and when it (actually) is on them, how can they benefit then by their admonition?”

Quran 47:18 (Yusuf Ali Translation)
