Hadith 1896
حَدَّثَنَا عَمْرُو بْنُ رَافِعٍ، حَدَّثَنَا هُشَيْمٌ، عَنْ أَبِي بَلْجٍ، عَنْ مُحَمَّدِ بْنِ حَاطِبٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " فَصْلُ مَا بَيْنَ الْحَلاَلِ وَالْحَرَامِ الدُّفُّ وَالصَّوْتُ فِي النِّكَاحِ " .
It was narrated from Muhammad bin Hatib that the Messenger of Allah said:“What differentiates between the lawful and the unlawful is (beating) the Daff and raising the voices (in song) at the time of marriage.”
