It is narrated from Sayyiduna Sahl bin Sa'd (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whenever anyone calling out the talbiyah calls it out, every tree and stone on his right and on his left also calls out the talbiyah, until the earth, to its furthest extent on the right and on the left, resounds (with the same sound)." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
