A slave whose master gives him permission

It is narrated from Umayr that a slave had been given permission by his master for tailoring, and another slave for dyeing. Shurayh held both of them liable: he held the tailor liable for the price of the threads and needles, and he held the other liable for the dye and its boiling, and for whatever resembles these kinds of work.

Ibn Sirin says that if a slave is given permission for one kind of business and he trades in a kind other than that, then the debt is not upon him.

Hasan bin Salih says that if a slave is given permission to work in only one kind (of trade), then he has been given permission.
