Ikrimah narrates from Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) that a man came to the Prophet (peace and blessings be upon him), complaining that his master had married him off and now wanted to separate him from his wife. He (peace and blessings be upon him) praised and glorified Allah and said: "What is the matter with people who marry their slaves to their slave-women and then want to separate them? Indeed, the one who holds the authority of divorce is the one who takes hold of the shin," that is, the one whose wife she is.
