 ٥ـ عَلِيُّ بْنُ مُحَمَّدٍ عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ جَعْفَرِ بْنِ مُحَمَّدِ بْنِ حَمْزَةَ قَالَ كَتَبْتُ إِلَى الرَّجُلِ (عَلَيْهِ السَّلام) أَسْأَلُهُ أَنَّ مَوَالِيَكَ اخْتَلَفُوا فِي الْعِلْمِ فَقَالَ بَعْضُهُمْ لَمْ يَزَلِ الله عَالِماً قَبْلَ فِعْلِ الاشْيَاءِ وَقَالَ بَعْضُهُمْ لا نَقُولُ لَمْ يَزَلِ الله عَالِماً لانَّ مَعْنَى يَعْلَمُ يَفْعَلُ فَإِنْ أَثْبَتْنَا الْعِلْمَ فَقَدْ أَثْبَتْنَا فِي الازَلِ مَعَهُ شَيْئاً فَإِنْ رَأَيْتَ جَعَلَنِيَ الله فِدَاكَ أَنْ تُعَلِّمَنِي مِنْ ذَلِكَ مَا أَقِفُ عَلَيْهِ وَلا أَجُوزُهُ فَكَتَبَ (عَلَيْهِ السَّلام) بِخَطِّهِ لَمْ يَزَلِ الله عَالِماً تَبَارَكَ وَتَعَالَى ذِكْرُهُ.
 5. Ali ibn Muhammad has narrated from Sahl ibn Ziyad from Ja‘far ibn Muhammad ibn Hamzah who has said the following. “I wrote to the man (Imam , ‘Your followers differ about the knowledge of Allah. There are those who say that before creating all things Allah had eternally full knowledge of them. Others say that we should not say so because His knowing is like His action. If we prove that His Knowledge is eternal we have also established another thing eternal along with Him. May Allah take my soul in service for your cause, if you would consider it proper, kindly enlighten me in this issue so that I would have a firm stand and do not waver therefrom.” He wrote in his own handwriting, “Eternally Allah , the Most Holy, the Most High has had the Knowledge of all things.” ?? and Allah’s Positive Attributes such as His knowledge are the same as His Essence without any duality between His Essence and His Positive Attributes).’ “
