Qatadah narrates from Khilas that Sayyiduna Ali (may Allah be pleased with him) used to hold the hired worker liable.
Jabir al-Ju'fi, who is da'if (weak), narrated from al-Sha'bi that Sayyiduna Ali (may Allah be pleased with him) used to hold the hired worker liable.
The narration of Ja'far from his father from Ali is mursal, and the scholars of hadith consider the narrations of Khilas from Ali weak.
