Some Jews came to the Holy Prophet (s.a.w.a.) and said: “O Muhammad, command this mountain to testify for your prophethood. If it testifies, we would also followsuit and embrace faith.”
The Prophet (s.a.w.a.) said:
“I will go to any mountain you like to make it testify
and it would also testify.”
So, they went to a mountain and said: “Make this mountain
testify.” So the Prophet (s.a.w.a.) commanded that mountain to
testify for his prophethood. It moved and testified in such a loud
voice that all heard it. It also testified that Holy Prophet (s.a.w.a.)
was superior to all creatures.
The mountain said: “O Muhammad, if you request your Lord to
change human beings into monkeys and pigs, He would do so. If you
request Him to make the sky reach the earth or the earth to reach the
sky, He would fulfill it. Almighty Allah has made the earth, heavens,
mountains, rivers, winds, lightning, animals and everything else
obedient to you. Whatever you command would be obeyed.”
