It is narrated from Hazrat Anas (may Allah be pleased with him) that once I was sitting behind Hazrat Abu Talha (may Allah be pleased with him), and it was so close that Hazrat Abu Talha's (may Allah be pleased with him) knee was about to touch the knee of the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) was reciting the Talbiyah for both Hajj and Umrah while proceeding.
