Hadith.4555 - Ismail ibn Abi Ziyad narrated from Imam Jafar ibn Muhammad Al-Sadiq (as) from his father, Imam Muhammad ibn Ali Al-Baqir (as), from his forefathers (peace be upon them) that the Messenger of Allah (swt) (peace and blessings be upon him and his family) said: "Any free woman who marries herself to a slave without the permission of his masters has made her private parts permissible unlawfully, and she is not entitled to a dowry."

Hadith.4556 - Al-Hasan ibn Mahbub narrated from Malik ibn Atiyyah, from Dawud ibn Farqad, from Abu Abdillah (as), who said: I asked him about a man who purchased a mature bondwoman who had not menstruated while with him for six months, and there was no sign of pregnancy. Imam (as) said: "If it is customary for someone like her to menstruate, and her condition is not due to old age, then this is a defect for which she can be returned."

Hadith.4557 - Aban ibn Uthman narrated from Al-Hasan al-Sayqal, from Abu Abdillah (as), who said: I heard him being asked about a man who purchased a bondwoman and had relations with her before observing an istibra' (waiting period) to ensure she was not pregnant. Imam (as) said: "What he did was wrong. He should seek forgiveness from Allah (swt) and not repeat it." Then it was said: "What if he sold her to another man, who also had relations with her without observing an istibra'? Then the second man sold her to a third man, who also had relations with her without observing an istibra', and it later became clear that she was pregnant while with the third man?" Abu Abdillah (as) said: "The child belongs to the [current] owner of the bed (al-firash), and for the adulterer (al-ahir), there is nothing but loss (al-hajar)."
