gambling
6- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ النَّوْفَلِيِّ عَنِ السَّكُونِيِّ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) قَالَ كَانَ يَنْهَى عَنِ الْجَوْزِ يَجِي‏ءُ بِهِ الصِّبْيَانُ مِنَ الْقِمَارِ أَنْ يُؤْكَلَ وَقَالَ هُوَ سُحْتٌ.
6. Ali ibn Ibrahim has narrated from his father from al-Nawfaliy from al-Sakuniy who has said the following: “Abu ‘Abd Allah (a.s.), would prohibit utilization of walnuts, that children bring after using in gambling, saying that it is Suht (filthy), unlawful.’”
