ما يوجِبُ الارتِطامَ فِي الرِّبا That Which Leads One to Become Involved in Usury

8ـ الإمامُ عليٌّ (عَلَيهِ الّسَلامُ): مَعاشِرَ الناسِ ، الفِقهَ ثُمَّ المَتجَرَ ، واللّه‏ِ لَلرِّبا في هذِهِ الاُمَّةِ أخفى من دَبِيبِ النَّملِ عَلى الصَّفا.

8- Imam Ali (AS) said, 'Engage yourself firstly in communal relations with people, then the law, and subsequently trading, for by Allah, usury creeps into this community more discreetly than an ant creeps onto a rock.’[Bihar al-Anwar, v. 103, p. 117, no. 16]
 

9ـ الإمامُ عليٌّ (عَلَيهِ الّسَلامُ): مَنِ اتَّجَرَ بغَيرِ فِقهٍ فَقَدِ ارتَطَمَ في الرِّبا.

9– Imam Ali (AS) said, 'Whoever trades without knowledge of legal rulings gets involved in usury.’[Nahj al-Balagha, Saying 447]
