6ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ جَمِيلِ بْنِ دَرَّاجٍ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيهِ السَّلام) عَنِ الإيمَانِ فَقَالَ شَهَادَةُ أَنْ لا إِلَهَ إِلا الله وَأَنَّ مُحَمَّداً رَسُولُ الله قَالَ قُلْتُ أَ لَيْسَ هَذَا عَمَلٌ قَالَ بَلَى قُلْتُ فَالْعَمَلُ مِنَ الإيمَانِ قَالَ لا يَثْبُتُ لَهُ الإيمَانُ إِلا بِالْعَمَلِ وَالْعَمَلُ مِنْهُ.
6. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from Ibn Abi ‘Umayr from Jamil ibn Darraj who has said the following: “I asked Abu ‘Abdillah about belief. He said, ‘It is to testify that no one deserves to be worshipped except Allah and that Muhammad is the Messenger of Allah.’ I asked, ‘Is it not a deed?’ He said, ‘Yes, it is a deed.’ 1 then asked, ‘Is deed of belief?’ He said, ‘One’s belief does not take any root without deed and deed is from belief.’”
