Chapter 22 | On What al-Ridha (s) Said About Faith That Is Recognition of Paradise, Verbal Confession and Physical Action
3 - حَدَّثَنا مُحَمَّدِ بْنِ الحَسَن بْنِ أَحْمَدِ بْنِ الوَلِيد رَضِىَ اللهُ عَنْهُ قالَ: حَدَّثَنا مُحَمَّدِ بْنِ الحَسَن الصَفَّار عَن أَحْمَدِ بْنِ مُحَمَّدِ بْنِ عِيسَى عَن بَكْرِ بْنِ صالِح الرَّازِيُّ، عَن أَبي الصَّلْتِالهَرَوِيِّ قالَ سَأَلْت الرِّضا a.sُ، عَنِ الإِيمان فَقالَ a.sُ: الإِيمان عَقدٌ بِالقَلب وَلَفظٌ بِاللِّسانِ وَعَمَلٌ بِالجَوارِح لا يَكُونُ الإيمانُ إِلاّ هكَذا.

He (s) said, ‘Faith is belief in the heart, expression by the tongue and enacting by the body parts. Anything else would not be faith.’”
