That the Messenger of Allah ﷺ said: "Do not sell the (slave) female singers, not purchase them, nor teach them (to sing). And there is no good in trading in them, and their prices are unlawful. It was about the likes of this that this Ayah was revealed: And among mankind is he who purchases idle talk to divert from the way of Allah." [He said:] There is narration about this from 'Umar bin Al-Khattab.  

عَنْ رَسُولِ اللَّهِ ﷺ قَالَ لاَ تَبِيعُوا الْقَيْنَاتِ وَلاَ تَشْتَرُوهُنَّ وَلاَ تُعَلِّمُوهُنَّ وَلاَ خَيْرَ فِي تِجَارَةٍ فِيهِنَّ وَثَمَنُهُنَّ حَرَامٌ فِي مِثْلِ هَذَا أُنْزِلَتْ هَذِهِ الآيَةُ ( وَمِنَ النَّاسِ مَنْ يَشْتَرِي لَهْوَ الْحَدِيثِ لِيُضِلَّ عَنْ سَبِيلِ اللَّهِ ) إِلَى آخِرِ الآيَةِ قَالَ وَفِي الْبَابِ عَنْ عُمَرَ بْنِ الْخَطَّابِ  

[Machine] The Messenger of Allah ﷺ said, "It is not permissible to engage in the trade of female singers or to buy and sell them, and it is forbidden to make any business transactions involving them, as their price is prohibited." And he recited this verse, "And among the people is he who buys the amusement of speech to mislead [others] from the way of Allah without knowledge."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «لَا يَحِلُّ شَرْيُ الْمُغَنِّيَاتِ وَلَا بَيْعُهُنَّ وَلَا تِجَارَةٌ فِيهِنَّ وَثَمَنُهُنَّ حَرَامٌ» وَتَلَا هَذِهِ الْآيَةَ {وَمِنَ النَّاسِ مَنْ يَشْتَرِي لَهْوَ الْحَدِيثِ لِيُضِلَّ عَنْ سَبِيلِ اللهِ بِغَيْرِ عَلِمٍ} الْآيَةَ  

"لا تَبِيعُوا الْقَيْنَات وَلَا تَشْتَرُوهُنَّ، وَلا تُعَلِّمُوهُنَّ، ولَا خَيرَ فِي تجارَةٍ فِيهنَّ، وَثَمَنُهُنَّ حَرامٌ، في مِثْلِ هَذَا أُنزِلَتْ هَذه الآيَةُ {وَمِنَ النَّاسِ مَنْ يَشْتَرِي لَهْوَ الْحَدِيثِ. إلخ} ".
