Hadith 5682- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ النَّوْفَلِيِّ عَنِ السَّكُونِيِّ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) قَالَ إِذَا نَظَرَ الرَّجُلُ فِي تِجَارَةٍ فَلَمْ يَرَ فِيهَا شَيْئاً فَلْيَتَحَوَّلْ إِلَى غَيْرِهَا.
2. Ali ibn Ibrahim has narrated from his father from al-Nawfaliy from al-Sakuniy who has said the following: “Abu ‘Abd Allah (a.s.), has said, ‘If one starts a certain business, if he does not find any profit in it, he then must change it for another kind of business.’”
