3ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ خَالِدٍ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ أَبِي نَصْرٍ عَنْ بَعْضِ رِجَالِهِ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ أَفْضَلُ الْعِبَادَةِ إِدْمَانُ التَّفَكُّرِ فِي الله وَفِي قُدْرَتِهِ.
3. A number of our people have narrated from Ahmad ibn Muhammad ibn Khalid from Ahmad ibn Muhammad ibn abu Nasr from certain individuals of his people from Abu ‘Abdillah عليه السلام who has said the following: “Abu ‘Abd Allah عليه السلام has said, ‘The most virtuous form of worship is thinking about Allah very often and about His power. ’”
