Hadith 26:188
It was narrated that 'Amir bin Sa'd said:
"I entered upon Qurazah bin Ka'b and Abu Mas'ud Al-Ansari during a wedding and there were some young girls singing. I said: 'You are two of the Companions of the Messenger of Allah who were present at Badr, and this is being done in your presence!' They said: 'Sit down if you want and listen with us, or if you want you can go away. We were granted a concession allowing entertainment at weddings.'"
أَخْبَرَنَا عَلِيُّ بْنُ حُجْرٍ، قَالَ حَدَّثَنَا شَرِيكٌ، عَنْ أَبِي إِسْحَاقَ، عَنْ عَامِرِ بْنِ سَعْدٍ، قَالَ دَخَلْتُ عَلَى قَرَظَةَ بْنِ كَعْبٍ وَأَبِي مَسْعُودٍ الأَنْصَارِيِّ فِي عُرْسٍ وَإِذَا جَوَارٍ يُغَنِّينَ فَقُلْتُ أَنْتُمَا صَاحِبَا رَسُولِ اللَّهِ صلى الله عليه وسلم وَمِنْ أَهْلِ بَدْرٍ يُفْعَلُ هَذَا عِنْدَكُمْ . فَقَالاَ اجْلِسْ إِنْ شِئْتَ فَاسْمَعْ مَعَنَا وَإِنْ شِئْتَ اذْهَبْ قَدْ رُخِّصَ لَنَا فِي اللَّهْوِ عِنْدَ الْعُرْسِ
