Sayyiduna al-Fadl (may Allah be pleased with him) said that the Prophet (peace and blessings be upon him) kept saying the Talbiyah until he stoned the Jamrah.
It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) came to the Jamrah that was by the tree and threw seven pebbles at it, saying the Takbir with each pebble. Likewise, in the established narration from Sayyiduna Ibn Mas'ud (may Allah be pleased with him), he (peace and blessings be upon him) said the Takbir with each pebble.
