فَهَلۡ يَنظُرُونَ إِلَّا ٱلسَّاعَةَ أَن تَأۡتِيَهُم بَغۡتَةٗۖ فَقَدۡ جَآءَ أَشۡرَاطُهَاۚ فَأَنَّىٰ لَهُمۡ إِذَا جَآءَتۡهُمۡ ذِكۡرَىٰهُمۡ ١٨
Then do they await except that the Hour should come upon them unexpectedly? But already there have come [some of] its indications. Then how [i.e., what good] to them, when it has come, will be their remembrance?
Translation: Saheeh International (English)
Each word's meaning and sound
Are the disbelievers waiting for anything but the hour to come on them suddenly without their having any prior knowledge of it? Its signs have already come, such as the mission of the Prophet (peace be upon him) and the splitting of the moon. How will they then take heed when the hour comes? It is unlikely that the reminder will be of benefit to them.
