There is no one who makes talbiyyah except that ..

There is no one who makes talbiyyah except that whatever is on his right and left – trees and stones also make talbiyyah until the earth resounds from here and here – meaning – on his right and left.”

18. And he continually repeats the talbiyyah as it is “from the signs of Hajj”(25) and because of the Prophet’s saying:

“There is no one who makes talbiyyah except that whatever is on his right and left – trees and stones also make talbiyyah until the earth resounds from here and here – meaning – on his right and left.”(26)

Especially whenever he ascends a high place or descends a valley – according to the hadith which has preceded: “It is as if I am looking at Musa – upon whom be peace – coming down from the mountain pass….loudly reciting talbiyyah” and in the other hadith: “It is if I am looking towards him when he descends in the valley reciting talbiyyah”.
