Mishkat al-Masabih 22 Clothing كتاب اللباس 187

وَعَنْ بُرَيْدَةَ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «مَنْ لَعِبَ بِالنَّرْدَشِيرِ فَكَأَنَّمَا صَبَغَ يَدَهُ فِي لَحْمِ خِنْزِيرٍ وَدَمِهِ» . رَوَاهُ مُسْلِمٌ

Buraida reported the Prophet as saying, “He who plays backgammon is as though he had dipped his hand in a pig’s flesh and blood.” Muslim transmitted it.
