It is narrated from Hazrat Khallas (may Allah have mercy on him) that a slave girl came to the tribe of Tayy. She claimed that she was free, and considering her free, a man married her. Then the master of the slave girl came to take her back. Hazrat Uthman (may Allah be pleased with him) decided that the slave girl and her children would go to the master, and for her husband, he would have whatever he had gained from the belongings. Then he established among the people this practice that for every soul there are two souls.
