The Mountain of Uhud's Shaking

Have you ever heard that a solid body fell in love? It is normal that a human likes the appearance of a wall because of its beauty, but it is very strange that a wall expresses its love for a human.
Aly ibn abi Taleb (may Allah be pleased with him) said : “After the invasion of Uhud a lot of Muslims left away from Uhud as seventy of the best of companions of the Prophet have been martyred in its shed and valley.
And when the Messenger of Allah ( peace be upon him] went to Uhud with Abu Bakr, Omar, and Uthman {in a version other than that omar and aly were with the Prophet}[ may Allah be pleased with them], he prayed for the martyrs of Uhud. Uhud waged suddenly, then the Messenger of Allah [PBUH] smiled and lift his pure leg hitting the mountain, and said ( stop).
Why did the mountain wage and why did it stop after the hit??
When the mountain felt the touch of the Messenger’s feet on his rocks, it began to chill in a happy way. Then it stopped for the sake of him.
