Assalam alaikum,
In Surat Hashar, verse 21(59:21) of the Holy Qur'an, Allah Subhanahu Wa Ta'ala says :--
"Had We sent down this Qur'an on a mountain,
Verily, you would have seen it humble itself and
cleave asunder".
If a mountain, for example mount Everest would be rendered to dust from that power, what do you think of the one carrying that power in his heart? It means we are not really understanding who is Sayyidina Muhammad, the Messenger of Allah, may Allah bless him and grant him peace. He is a human being, but not like you and me. He was able to receive the power behind all creation through his physical being. That is why Allah says:--
"Truly, you ( O Muhammad ) are of a sublime nature".
(Qur'an 68:4)
He never said anything from his own will....he has no will of his own, no ego. He is the example of perfect submission to Divine Will, Sallallahu alaihi Wasallam.
