Had We sent down this Qur’an on a mountain,
you would surely have seen it humbling itself
and rent asunder by the fear of Allah.
Such are the parables which We put forward to mankind that they may reflect.
In this ayah, Allah s.w.t. emphasizes the greatness of the Qur’an, its high status and of being worthy of making hearts humble and rent asunder upon hearing it, because of the true promises and sure threats that it contains.
Then if this is the case with a mountain which is hard and massive – that if it was made able to comprehend and understand this Qur’an – will feel humble and crumble from fear of Allah the Exalted, then what about you, O mankind? Why do your hearts not feel softness and humbleness from the fear of Allah, even though you understand Allah’s command and comprehend His Book?
If the solid mountains feel humble and are rent asunder from the fear of Allah, if it heard Allah’s Speech and comprehended it, what about you O mankind – who heard the Qur’an and understood it?
Allahumma, revive the state of our hearts!
