2 ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنْ مُحَمَّدِ بْنِ سِنَانٍ عَنِ ابْنِ مُسْكَانَ عَنْ حُسَيْنٍ الصَّيْقَلِ قَالَ سَمِعْتُ أَبَا عَبْدِ الله (عَلَيْهِ السَّلام) يَقُولُ لا يَقْبَلُ الله عَمَلاً إِلا بِمَعْرِفَةٍ وَلا مَعْرِفَةَ إِلا بِعَمَلٍ فَمَنْ عَرَفَ دَلَّتْهُ الْمَعْرِفَةُ عَلَى الْعَمَلِ وَمَنْ لَمْ يَعْمَلْ فَلا مَعْرِفَةَ لَهُ أَلا إِنَّ الايمَانَ بَعْضُهُ مِنْ بَعْضٍ.
2. Muhammad ibn Yahya from Ahmad ibn Muhammad ibn ‘Isa from Muhammad ibn Sinan from ibn Muskan from Hassan al-Sayqal who has said the following. “(Imam) abu ‘Abdallah 
who has said, “Allah does not accept a deed without good understanding and proper understanding does not come into being without work. One who achieves proper understanding it will guide him to good deeds and one who does not work will not have any understanding. Is it not a fact that parts of faith comes from other parts?”
