Verse 21

لَوْ أَنزَلْنَا هَـٰذَا ٱلْقُرْءَانَ عَلَىٰ جَبَلٍ لَّرَأَيْتَهُۥ خَـٰشِعًا مُّتَصَدِّعًا مِّنْ خَشْيَةِ ٱللَّهِ وَتِلْكَ ٱلْأَمْثَـٰلُ نَضْرِبُهَا لِلنَّاسِ لَعَلَّهُمْ يَتَفَكَّرُونَ

Had We revealed this Quran to a mountain, you would have seen it humbling itself reverently due to fear of God. And these are examples that We cite for the people that they may think.
