Regarding One Who Acquires A Mahram Relative As A Slave
Arabic hadith text
حَدَّثَنَا مُحَمَّدُ بْنُ سُلَيْمَانَ، حَدَّثَنَا عَبْدُ الْوَهَّابِ، عَنْ سَعِيدٍ، عَنْ قَتَادَةَ، عَنِ الْحَسَنِ، قَالَمَنْ مَلَكَ ذَا رَحِمٍ مَحْرَمٍ فَهُوَ حُرٌّ ‏.‏
Translation
Qatadah reported 'Umar b. al-Khattab (ra) as saying

If anyone gets possession of a relative who is within the prohibited degrees, that person becomes free.
