] This Hadith is Hasan Sahih. This is acted upon according to some of the people of knowledge among the Companions of the Prophet (ﷺ) and others. They did not think that an embellished (silver-gilded) sword could be sold for Dirham, nor a silver-plated waist-band, or something similar, until it (the silver) was distinguished and separated. This is the view of Ibn al-Mubarak, Ash-Shafi'i, Ahmad and Ishaq.
حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا ابْنُ الْمُبَارَكِ، عَنْ أَبِي شُجَاعٍ، سَعِيدِ بْنِ يَزِيدَ بِهَذَا الإِسْنَادِ نَحْوَهُ . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ . وَالْعَمَلُ عَلَى هَذَا عِنْدَ بَعْضِ أَهْلِ الْعِلْمِ مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم وَغَيْرِهِمْ لَمْ يَرَوْا أَنْ يُبَاعَ السَّيْفُ مُحَلًّى أَوْ مِنْطَقَةٌ مُفَضَّضَةٌ أَوْ مِثْلُ هَذَا بِدَرَاهِمَ حَتَّى يُمَيَّزَ وَيُفَصَّلَ . وَهُوَ قَوْلُ ابْنِ الْمُبَارَكِ وَالشَّافِعِيِّ وَأَحْمَدَ وَإِسْحَاقَ . وَقَدْ رَخَّصَ بَعْضُ أَهْلِ الْعِلْمِ فِي ذَلِكَ مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم وَغَيْرِهِمْ .
