A slave and his wife live on a livelihood, and this is the end of their struggles. For nothing is greater than uniting two people in lawful marriage. Among these is what is narrated about Abu Bakr al-Siddiq, may Allah be pleased with him. In his days of seclusion, he used to roam the city of Medina at night to observe the conditions of the people, to know the oppressed from the oppressor, and to mingle with their groups. Then he heard a slave girl singing and reciting poetry: From Al-Kamil: "My heart is broken, my joy is gone, like a soft branch. Her face was like the full moon, appearing and disappearing from the Hashimite lineage."

So, may Allah be pleased with him, he knocked on the door and asked who she was. She replied, "Go away from me." He said, "You must tell me." She said to him, "By the right of the one who brought the Quran, will you leave me alone?" He said, "By God, I will not leave Mecca until you tell me." She sighed and said, "I am the one who was freed by the Arabs before her." She mentioned the love of Muhammad ibn al-Qasim. He asked her, "Are you free?" She said, "No, but a slave." He asked, "To whom?" She said, "To so-and-so, I have sold myself to him." So, may Allah be pleased with him, he went away. When morning came, he asked about Muhammad ibn al-Qasim and found him in Iraq. He said, "I will buy her and buy her from him and send her to Muhammad ibn al-Qasim in Iraq." He wrote him the story and then said, "And know, my son, that many a sick person has died because of them, and many a one has perished."
