Whoever emancipates a share in a slave should completely emancipate him from his money, if he can afford it. Otherwise, a fair price should be set for the slave.

If one of the joint owners of a slave decides to emancipate his share of that slave, he should pay to completely emancipate him, if he can afford that, by paying to his partners the value of their shares of that slave in order for him to be free. However, if he cannot do so, whether because he does not have money, or he has money but it is not enough, or this would harm him, then, in such case, the slave should be given two options to choose from: 1. to remain partly slave and partly free. 2. to work in order to pay for his freedom after a fair price is set for him. This procedure is known as Istis‘ā’.
