Sayyiduna Talq bin Ali (may Allah be pleased with him) narrated: I came to the Prophet (peace and blessings be upon him) and his (peace and blessings be upon him) Companions while they were building the mosque. When I saw their work, I took hold of the spade and began mixing the clay with it. It seemed that my handling of the spade pleased him (peace and blessings be upon him), while they (the other Companions) kept on working. He (peace and blessings be upon him) said: "Leave the Hanafi to the clay, for he is the best of you at handling clay." (This wording is from the narration of Asim bin Ali.)
