The Book of Manumission of Slaves
31/7. Chapter:
Regarding One Who Acquires A Mahram Relative As A Slave
Sunan Abi Dawud
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ سَعِيدٍ، عَنْ قَتَادَةَ، عَنْ جَابِرِ بْنِ زَيْدٍ، وَالْحَسَنِ، مِثْلَهُ . قَالَ أَبُو دَاوُدَ سَعِيدٌ أَحْفَظُ مِنْ حَمَّادٍ .
A similar tradition has also been transmitted by Jabir b. Zaid and al-Hasan through a different chain of narrators. Abu Dawud said: The narrator sa'id retained te tradition more carefully than Hammad.
