Why not? Muhammad bought slaves: “Jabir (Allah be pleased with him) reported: There came a slave and pledged allegiance to Allah’s Apostle (may peace be upon him) on migration; he (the Holy Prophet) did not know that he was a slave. Then there came his master and demanded him back, whereupon Allah’s Apostle (may peace be upon him) said: Sell him to me. And he bought him for two black slaves, and he did not afterwards take allegiance from anyone until he had asked him whether he was a slave (or a free man).” (Muslim 3901)
Muhammad took female Infidel captives as slaves: “Narrated Anas: The Prophet offered the Fajr Prayer near Khaibar when it was still dark and then said, ‘Allahu-Akbar! Khaibar is destroyed, for whenever we approach a (hostile) nation (to fight), then evil will be the morning for those who have been warned.’ Then the inhabitants of Khaibar came out running on the roads. The Prophet had their warriors killed, their offspring and woman taken as captives. Safiya was amongst the captives. She first came in the share of Dahya Alkali but later on she belonged to the Prophet. The Prophet made her manumission as her ‘Mahr.’” (Bukhari 5.59.512) Mahr is bride price: Muhammad freed her and married her. But he didn’t do this to all his slaves:
Muhammad owned slaves: “Narrated Anas bin Malik: Allah’s Apostle was on a journey and he had a black slave called Anjasha, and he was driving the camels (very fast, and there were women riding on those camels). Allah’s Apostle said, ‘Waihaka (May Allah be merciful to you), O Anjasha! Drive slowly (the camels) with the glass vessels (women)!’” (Bukhari 8.73.182) There is no mention of Muhammad’s freeing Anjasha.
“El Cajon couple accused of trafficking housekeeper,” by Kristina Davis, San Diego Union Tribune, April 8, 2016:
San Diego — A handwritten note asking a nurse for help has led to labor trafficking charges against an Iraqi couple who are accused of forcing an Indonesian housekeeper to work without pay in their El Cajon apartment.
Her rescue a few days later is the first time in more than five years the woman, referred to in court documents only as W.M., has been free of indentured servitude, authorities said Friday.
“Today’s arrests bring to light the sad reality of modern day slavery,” Dave Shaw, special agent in charge for U.S. Homeland Security Investigations in San Diego, said in a statement. “… Forced labor, which often involves individuals who are held in isolation, degraded, and most alarming — stripped of their basic human freedom — has no place in a modern society.”
Firas Majeed and his wife, Shatha Abbas, pleaded not guilty in San Diego federal court Friday. They are charged with forced labor, trafficking and confiscating a passport.
The housekeeper pleaded for help in a note to a nurse on March 18, and the note made it to homeland security agents, according to the complaint.
Agents went to the apartment on Mollison Avenue days later on the ruse of an immigration compliance check and spoke to the housekeeper, whose age was not released. Once away from her alleged captors, she explained through an interpreter what her life has been like over the past five years.
She said she sought a job through an employment agency in Indonesia and began to work for an Iraqi man, Dr. Haider Kubba, and his large extended family in Dubai in 2010. She lived with them, working 20 hours a day, seven days a week, for five years, the complaint says.
She cleaned, did laundry, cooked and took care of the children — but was not allowed to leave the house on her own, with the doors and windows being locked while Kubba went to work, she said, according to the complaint. The exception was being allowed to take the trash out, with permission.
The housekeeper said she was never paid for her work, although her employers sporadically sent unknown amounts money to her mother in Indonesia, and some years had passed without payments….
