[Machine] I heard the Messenger of Allah ﷺ saying while on the pulpit: "The Banu Hashim ibn Al-Mughirah sought permission from me to marry their daughter to Ali ibn Abi Talib, but I did not grant permission. Then again, they sought permission, but I did not grant permission. My daughter is a part of me; I feel uneasy about what disturbs her and it hurts me for what hurts her." Qutaybah narrated in Sahih that Al-Laith reported that they discussed it and concluded that if a slave owns himself by paying off his debt or by buying his freedom, he will set free some of himself. Similarly, when a free man owns his child, he will therefore own part of himself. If a father owns his child, he would own a part of him. Therefore, it becomes obligatory for him to set his child free.  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ وَهُوَ عَلَى الْمِنْبَرِ إِنَّ بَنِي هِشَامِ بْنِ الْمُغِيرَةِ اسْتَأْذَنُونِي فِي أَنْ يُنْكِحُوا ابْنَتَهُمْ عَلِيَّ بْنَ أَبِي طَالِبٍ فَلَا آذَنُ ثُمَّ لَا آذَنُ وَإِنَّمَا ابْنَتِي بَضْعَةٌ مِنِّي يَرِيبُنِي مَا رَابَهَا وَيُؤْذِينِي مَا آذَاهَا أَخْرَجَاهُ فِي الصَّحِيحِ عَنْ قُتَيْبَةَ عَنِ اللَّيْثِ فَأَخْبَرَ أَنَّ وَلَدَهُ بَعْضٌ مِنْهُ وَالْعَبْدُ إِذَا مَلَكَ نَفْسَهُ بِأَدَاءِ مَالِ الْكِتَابَةِ أَوْ بِابْتِيَاعِ نَفْسِهِ عَتَقَ فَكَذَلِكَ الْحُرُّ إِذَا مَلَكَ وَلَدَهُ فَقَدْ مَلَكَ بَعْضَهُ وَإِذَا مَلَكَ وَالِدَهُ فَقَدْ مَلَكَ مَنْ هُوَ بَعْضٌ مِنْهُ فَوَجَبَ أَنْ يَعْتِقَ
