It is narrated from Hazrat Sulaiman bin Yasar, may Allah have mercy on him, that a slave woman (after migrating) came to a certain people and deceived them, telling them that she was free. A man married her and had some children with her. Later it became known that she was actually a slave woman. So Hazrat Umar, may Allah be pleased with him, decided that the value of her children should be paid, stating that every person who is deceived in this way should be compensated with a penalty of a slave (male or female).
