Quran 47:18 from Surah Muhammad on Divine Marvels.
فَهَلۡ يَنظُرُونَ إِلَّا ٱلسَّاعَةَ أَن تَأۡتِيَهُم بَغۡتَةٗۖ فَقَدۡ جَآءَ أَشۡرَاطُهَاۚ فَأَنَّىٰ لَهُمۡ إِذَا جَآءَتۡهُمۡ ذِكۡرَىٰهُمۡ
English translation: Then do they wait but (for) the Hour that it should come to them suddenly But indeed have come its indications Then how to them when has come to them their reminder
Transliteration: fahal yanzuruna illa al-sa'ata an tatiyahum baghtatan faqad jaa ashratuha fa-anna lahum idha jaathum dhik'rahum
