2. A number of our people have narrated from Ahmad ibn Muhammad ibn Khalid from his father from Wahab who has said the following
“Abu ‘Abd Allah (a.s.), has said that ’Amir al-Mu’minin has said, ‘If one uses the services of the slave of a people and causes damage to him, he is responsible. If one uses the works of a small free person and causes damage to that person, he is responsible.”’
