Sayyiduna Ibn Umar (may Allah be pleased with them both) did not see any harm in a slave establishing relations with a slave woman with the permission of his master.

Brief Explanation
Hajjaj ibn Arta’ah: Truthful, but a mudallis (one who practices tadlis), and makes many mistakes.
Issue: Can a slave practice tasarri (have relations with a slave woman)?
Foundational Principle: Tasarri (i.e., having relations with a slave woman) is permissible for the owner. Since a slave himself is not an owner, therefore: the slave woman is not a “lawful object of intercourse” for him, unless the owner grants permission.
The statement of Sayyiduna Ibn ‘Umar radi Allahu anhuma is an ijtihadi fatwa that: “If the master grants permission, then the slave may also practice tasarri.”
Among the jurists of the Hanafis and Malikis, this issue is disputed:
Fiqhi School ◄ Position Hanafis: The slave cannot practice tasarri, because he is not the owner. Some Malikis and Ahl al-Zahir consider it permissible with permission, as is the statement of Ibn ‘Umar.
✅ Conclusion: This athar is weak in its chain (due to Hajjaj ibn Arta’ah), but in terms of content, it expresses a valid juristic opinion, which is the fatwa of a jurist Companion like Ibn ‘Umar radi Allahu anhuma.
