[Machine] The Messenger of Allah ﷺ said: "It is not permissible to buy or sell female singers, nor engage in any trade involving them. Consuming their earnings is Haram." In another narration by Bakr bin Mudar, the Messenger of Allah ﷺ said: "Do not sell or buy female singers, do not teach them, and there is no good in any trade involving them. Their earnings are Haram." A similar Hadith was revealed in the Quran in Surah Luqman, verse 6: "And among the people is he who sells his wordly life for the sake of idle talk, distracting others from the path of Allah without knowledge and who adopts it for amusement. Those will have a humiliating punishment." (Luqman 6)  

قَالَ رَسُولُ اللهِ ﷺ لَا يَحِلُّ بَيْعُ الْمُغَنِّيَاتِ وَلَا شِرَاؤُهُنَّ وَلَا تِجَارَةٌ فِيهِنَّ وَأَكْلُ أَثْمَانِهِنَّ حَرَامٌ وَفِي رِوَايَةِ بَكْرِ بْنِ مُضَرَ عَنْ رَسُولِ اللهِ ﷺ قَالَ لَا تَبِيعُوا الْمُغَنِّيَاتِ وَلَا تَشْتَرُوهُنَّ وَلَا تُعَلِّمُوهُنَّ وَلَا خَيْرَ فِي تِجَارَةٍ فِيهِنَّ وَثَمَنُهُنَّ حَرَامٌ وَفِي مِثْلِ هَذَا الْحَدِيثِ نَزَلَتْ {وَمِنَ النَّاسِ مَنْ يَشْتَرِي لَهْوَ الْحَدِيثِ} [لقمان 6] حَتَّى بَلَغَ {أُولَئِكَ لَهُمْ عَذَابٌ مُهِينٌ} [لقمان 6]
