Almuntakhab Fi Tafsir Alquran Alkarim

Had We revealed this Quran to a mountain and it could perceive the picture of what it represents and the complete glory in which it reveals itself, you would see it shaking with such fits of awe and shivering into atoms for the profound reverence dutiful to Allah. Such parables do We discourse to people that they may hopefully ponder, and that they may hopefully think and reflect before they act

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(59:21) Had We sent down this Qur'an upon a mountain you would indeed have seen it humbling itself and breaking asunder out of fear of Allah. *31 We propound such parables to people that they may reflect.

*31) The parable means that if a huge creation like a mountain had the sense and knowledge that it had been made responsible and accountable, like man, before Allah Almighty, for its deeds, it would have trembled from the fear of it. But how heedless, senseless and thoughtless is the man, who understands the Qur'an, and has known the whole truth through it, yet he is neither seized by any fear not feels worried as to what answer he would make to his God about the responsibilities that have been placed on him. On the contray when be reads the Qur'an, or hears it read, he remains. go un-moved as if he were a lifeless and senseless stone, which is not supposed to hear and see and understand anything. (For further explanation, see E.N. 120 of Surah AI-Ahzab)
