٥ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ يُونُسَ قَالَ سَأَلْتُ أَبَا الْحَسَنِ الرِّضَا (عَلَيهِ السَّلام) عَنِ الإيمَانِ وَالإسْلامِ فَقَالَ قَالَ أَبُو جَعْفَرٍ (عَلَيهِ السَّلام) إِنَّمَا هُوَ الإسْلامُ وَالإيمَانُ فَوْقَهُ بِدَرَجَةٍ وَالتَّقْوَى فَوْقَ الإيمَانِ بِدَرَجَةٍ وَالْيَقِينُ فَوْقَ التَّقْوَى بِدَرَجَةٍ وَلَمْ يُقْسَمْ بَيْنَ النَّاسِ شَيْ‏ءٌ أَقَلُّ مِنَ الْيَقِينِ قَالَ قُلْتُ فَأَيُّ شَيْ‏ءٍ الْيَقِينُ قَالَ التَّوَكُّلُ عَلَى الله وَالتَّسْلِيمُ لله وَالرِّضَا بِقَضَاءِ الله وَالتَّفْوِيضُ إِلَى الله قُلْتُ فَمَا تَفْسِيرُ ذَلِكَ قَالَ هَكَذَا قَالَ أَبُو جَعْفَرٍ (عَلَيهِ السَّلام).
5. Ali ibn Ibrahim has narrated from Muhammad ibn ‘Isa from Yunus who has said the following: “I asked abu al-Hassan al-Rida  about belief and Islam and he said, abu Ja’far  has said the following: ‘There is Islam. Belief is one degree higher above Islam, and piety is one degree higher above belief. Certainty is by one degree higher above piety and nothing is distributed among people so little as certainty is.’ I then said, ‘What then is certainty?’ The Imam said, ‘It is trust in Allah, submission to Allah, accepting the decision of Allah and allowing Allah to be the person in charge of one’s affairs.’ I then said, ‘What then is the interpretation of that?’ The Imam said, ‘This is how abu Ja’far  said it is.’”
