Caution: Translations of Quran and Ḥadīth may lead to possible misapplications and misinterpretations.

[Machine] "What has been made lawful for you from what was forbidden to you?" They said, "We are allowed to engage in the sale of the offspring's mothers." He said, "Do you both know Aba Hafs Umar?" They said, "Yes." He said, "Verily, Umar ibn Al-Khattab prohibited selling, gifting, or bequeathing them, but one can enjoy them as long as he is alive. When he dies, they become free." This narration was reported by the group from Abdullah bin Dinar, but some of the narrators made a mistake in it. So, it was elevated to the Prophet ﷺ, and it was a delusion that should not be mentioned.  

البيهقي:٢١٧٦٥وَأَخْبَرَنَا أَبُو الْحَسَنِ عَلِيُّ بْنُ أَحْمَدَ الْمُقْرِئُ ثنا أَحْمَدُ بْنُ سَلْمَانَ ثنا مُحَمَّدُ بْنُ غَالِبٍ ثنا أَبُو حُذَيْفَةَ ثنا سُفْيَانُ عَنْ عَبْدِ اللهِ بْنِ دِينَارٍ قَالَ جَاءَ رَجُلَانِ إِلَى ابْنِ عُمَرَ فَقَالَ مِنْ أَيْنَ أَقْبَلْتُمَا؟ قَالَا مِنْ قِبَلِ ابْنِ الزُّبَيْرِ فَأَحَلَّ لَنَا أَشْيَاءَ كَانَتْ تُحَرَّمُ عَلَيْنَا قَالَ

مَا أَحَلَّ لَكُمْ مِمَّا كَانَ يَحْرُمُ عَلَيْكُمْ؟ قَالَا أَحَلَّ لَنَا بَيْعَ أُمَّهَاتِ الْأَوْلَادِ قَالَ أَتَعْرِفَانِ أَبَا حَفْصٍ عُمَرَ ؓ؟ قَالَا نَعَمْ قَالَ فَإِنَّ عُمَرَ بْنَ الْخَطَّابِ ؓ نَهَى أَنْ تُبَاعَ أَوْ تُوهَبَ أَوْ تُورَثَ يَسْتَمْتِعُ بِهَا مَا كَانَ حَيًّا فَإِذَا مَاتَ فَهِيَ حُرَّةٌ هَكَذَا رَوَايَةُ الْجَمَاعَةِ عَنْ عَبْدِ اللهِ بْنِ دِينَارٍ وَغَلِطَ فِيهِ بَعْضُ الرُّوَاةِ عَنْ عَبْدِ اللهِ بْنِ دِينَارٍ فَرَفَعَهُ إِلَى النَّبِيِّ ﷺ وَهُوَ وَهْمٌ لَا يَحِلُّ ذِكْرُهُ
