لَوْ أَنزَلْنَا هَٰذَا ٱلْقُرْءَانَ عَلَىٰ جَبَلٍۢ لَّرَأَيْتَهُۥ خَٰشِعًۭا مُّتَصَدِّعًۭا مِّنْ خَشْيَةِ ٱللَّهِ ۚ وَتِلْكَ ٱلْأَمْثَٰلُ 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.
