Qur'an 59:21

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

If We had caused this Qur'an to descend upon a mountain, thou (O Muhammad) verily hadst seen it humbled, rent asunder by the fear of Allah. Such similitudes coin We for mankind that haply they may reflect.
