﴿ ۞ أَلَمْ يَأْنِ لِلَّذِينَ ءَامَنُوٓا۟ أَن تَخْشَعَ قُلُوبُهُمْ لِذِكْرِ ٱللَّهِ وَمَا نَزَلَ مِنَ ٱلْحَقِّ وَلَا يَكُونُوا۟ كَٱلَّذِينَ أُوتُوا۟ ٱلْكِتَٰبَ مِن قَبْلُ فَطَالَ عَلَيْهِمُ ٱلْأَمَدُ فَقَسَتْ قُلُوبُهُمْ ۖ وَكَثِيرٌۭ مِّنْهُمْ فَٰسِقُونَ ﴾

“IS IT NOT time that the hearts of all who have attained to faith should feel humble at the remem­brance of God and of all the truth that has been bestowed [on them] from on high, lest they become like those who were granted revelation aforetime, and whose hearts have hardened with the passing of time so that many of them are [now] depraved?”

When these verses were revealed, though Islam had not yet become a substantial power, it nevertheless had the full force of arguments and warnings behind it. Under these circumstances, one who did not feel the force of arguments and was not moved by Divine warnings is shown, by this, that he was suffering from a lack of awareness. Just as the earth becomes fresh and green when it receives water, so also should the individual awaken from his moral torpor when he hears clear arguments. How strange it is if he does not.
