It is narrated from Sayyiduna Sahl bin Sa'd (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "There is no believer who recites the talbiyah except that whatever tree or stone is on his right and his left recites the talbiyah with him, until the earth comes to an end from here and from there. Indeed, the people of the high ranks will be seen by those below them just as a star is seen in the sky."
