فَهَلْ يَنظُرُونَ إِلَّا ٱلسَّاعَةَ أَن تَأْتِيَهُم بَغْتَةًۭ ۖ فَقَدْ جَآءَ أَشْرَاطُهَا ۚ فَأَنَّىٰ لَهُمْ إِذَا جَآءَتْهُمْ ذِكْرَىٰهُمْ
Await they aught save the Hour, that it should come upon them unawares? And the beginnings thereof have already come. But how, when it hath come upon them, can they take their warning?
Surah Muhammad(47:18)

Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
"... And they became like the dry stubble of a fold-builder. And indeed, We have made the Qur'an easy to understand and remember; then is there any that will remember (or receive admonition) ." (V.54:31,32)
Narrated `Abdullah bin Masud:
The Prophet (ﷺ) used to recite: "Fahal-min-Maddakir (then is there any that will receive admonition?")
