4ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ خَالِدٍ عَنْ عَلِيِّ بْنِ أَسْبَاطٍ عَنْ مُحَمَّدِ بْنِ إِسْحَاقَ بْنِ الْحُسَيْنِ عَنْ عَمْرٍو عَنْ حَسَنِ بْنِ أَبَانٍ عَنْ أَبِي بَصِيرٍ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيهِ السَّلام) عَنْ حَدِّ الْعِبَادَةِ الَّتِي إِذَا فَعَلَهَا فَاعِلُهَا كَانَ مُؤَدِّياً فَقَالَ حُسْنُ النِّيَّةِ بِالطَّاعَةِ.
4. A number of our people have narrated from Ahmad ibn Muhammad ibn Khalid from Ali ibn Asbat from Muhammad ibn Ishaq ibn al-Husayn from Amr from Hassan ibn Aban from abu Basir who has said the following: “I asked Abu ‘Abdillah عليه السلام about worship, ‘What kind of worshipping sets the worshipper free from obligations.’ The Imam said, ‘It is obedience with good intention and in good faith.’”
