[Machine] The Messenger of Allah ﷺ came across slave girls who were singing, saying, "We greet you, you greet us back." The Messenger of Allah ﷺ stood and then called them, saying, "Do not say this, but instead say, 'May we be greeted and you.'" A man said, "O Messenger of Allah, are you granting permission for them to do this?" He replied, "Yes, indeed. It is a marriage, not adultery. Praise marriage."  

لَقِيَ رَسُولُ اللهِ ﷺ جَوَارِيَ يَتَغَنَّيْنَ يَقُلْنَ تُحَيُّونَا نُحَيِّيكُمْ فَوَقَفَ رَسُولُ اللهِ ﷺ ثُمَّ دَعَاهُنَّ فَقَالَ لَا تَقُولُوا هَكَذَا وَلَكِنْ قُولُوا حَيَّانَا وَإِيَّاكُمْ فَقَالَ رَجُلٌ يَا رَسُولَ اللهِ أَتُرَخِّصُ لِلنَّاسِ فِي هَذَا؟ قَالَ «نَعَمْ إِنَّهُ نِكَاحٌ لَا سِفَاحٌ أَشِيدُوا بِالنِّكَاحِ»
