The Imams know all the knowledge that has come to the angels, the prophets and the Messenger
4 Aḥadīth
Ali ibn Muhammad and Muhammad ibn al-Hassan from Sahl ibn Ziyad from Muhammad ibn al-Hassan ibn Shammun from ‘Abdallah ibn ‘Abd al-Rahman from ‘Abdallah ibn al-Qasim from Sama‘a from abu ‘Abdallah 
who has said the following. “Allah, the Most Holy, the Most High, has two kinds of knowledge. One kind is that which is revealed to the angels, the prophets the Messenger of Allah. Whatever is revealed to the angels, the Messenger of Allah and the prophets, is known to us also. The other is the kind which is exclusively for Allah. When Allah wants to make public anything from it is taught to us first and it is presented to the Imams before us also.” Ali ibn Muhammad and Muhammad ibn al-Hassan have narrated from Sahl ibn Ziyad from Musa ibn al-Qasim and Muhammad ibn Yahya from al-‘Amrakiy ibn Ali all of them from Ali ibn Ja‘far from his brother Musa ibn Ja‘far a similar Hadith.
عَلِيُّ بْنُ مُحَمَّدٍ وَمُحَمَّدُ بْنُ الْحَسَنِ عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ مُحَمَّدِ بْنِ الْحَسَنِ بْنِ شَمُّونٍ عَنْ عَبْدِ الله بْنِ عَبْدِ الرَّحْمَنِ عَنْ عَبْدِ الله بْنِ الْقَاسِمِ عَنْ سَمَاعَةَ عَنْ أَبِي عَبْدِ الله قَالَ إِنَّ لله تَبَارَكَ وَتَعَالَى عِلْمَيْنِ عِلْماً أَظْهَرَ عَلَيْهِ مَلائِكَتَهُ وَأَنْبِيَاءَهُ وَرُسُلَهُ فَمَا أَظْهَرَ عَلَيْهِ مَلائِكَتَهُ وَرُسُلَهُ وَأَنْبِيَاءَهُ فَقَدْ عَلِمْنَاهُ وَعِلْماً اسْتَأْثَرَ بِهِ فَإِذَا بَدَا لله فِي شَيْءٍ مِنْهُ أَعْلَمَنَا ذَلِكَ وَعَرَضَ عَلَى الائِمَّةِ الَّذِينَ كَانُوا مِنْ قَبْلِنَا. عَلِيُّ بْنُ مُحَمَّدٍ وَمُحَمَّدُ بْنُ الْحَسَنِ عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ مُوسَى بْنِ الْقَاسِمِ وَمُحَمَّدُ بْنُ يَحْيَى عَنِ الْعَمْرَكِيِّ بْنِ عَلِيٍّ جَمِيعاً عَنْ عَلِيِّ بْنِ جَعْفَرٍ عَنْ أَخِيهِ مُوسَى بْنِ جَعْفَرٍ (عَلَيْهما السَّلام) مِثْلَهُ.
A number of our people has narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from al-Qasim ibn Muhammad from Ali ibn abu Hamzah from abu Basir from abu ‘Abdallah who has said the following. “Allah, the Most Holy, the Most High, has two kinds of knowledge. One kind is His only and no creature knows about it. The other kind is that which He has thrown unto His angels and His Messenger. Whatever is thrown to the angels and the Messengers have reached us.”
عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ أَبِي حَمْزَةَ عَنْ أَبِي بَصِيرٍ عَنْ أَبِي عَبْدِ الله قَالَ إِنَّ لله عَزَّ وَجَلَّ عِلْمَيْنِ عِلْماً عِنْدَهُ لَمْ يُطْلِعْ عَلَيْهِ أَحَداً مِنْ خَلْقِهِ وَعِلْماً نَبَذَهُ إِلَى مَلائِكَتِهِ وَرُسُلِهِ فَمَا نَبَذَهُ إِلَى مَلائِكَتِهِ وَرُسُلِهِ فَقَدِ انْتَهَى إِلَيْنَا.
Ali ibn Ibrahim has narrated from Salih ibn al-Sindi from Ja‘far ibn Bashir from Durays who has said that he heard abu Ja‘far say the following. “Allah, the Most Holy, the Most High, has two kinds of knowledge. One kind is that which is granted and the kind is that which I withheld. Of the one which, is granted, nothing is known to the angels and the Messengers, but only we know it. The one which is withheld iis the kind that is before Allah, the Most Holy, the Most High in the original Book. When it appears it permeates.” come of Allah said:
عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ صَالِحِ بْنِ السِّنْدِيِّ عَنْ جَعْفَرِ بْنِ بَشِيرٍ عَنْ ضُرَيْسٍ قَالَ سَمِعْتُ أَبَا جَعْفَرٍ يَقُولُ إِنَّ لله عَزَّ وَجَلَّ عِلْمَيْنِ عِلْمٌ مَبْذُولٌ وَعِلْمٌ مَكْفُوفٌ فَأَمَّا الْمَبْذُولُ فَإِنَّهُ لَيْسَ مِنْ شَيْءٍ تَعْلَمُهُ الْمَلائِكَةُ وَالرُّسُلُ إِلا نَحْنُ نَعْلَمُهُ وَأَمَّا الْمَكْفُوفُ فَهُوَ الَّذِي عِنْدَ الله عَزَّ وَجَلَّ فِي أُمِّ الْكِتَابِ إِذَا خَرَجَ نَفَذَ.
Abu Ali al-Ash‘ari has narrated from Muhammad ibn ‘Abd al-Jabber from Muhammad ibn Isma‘il from Ali ibn al-Nu‘man from Suwayd al-Qalla from abu Ayyub from abu Basir from abu Ja‘far who has said the following. “Allah, the Most Holy, the Most High, has two kinds of knowledge. One kind of knowledge is that which no one knows except He. The other kind is that which He has taught to the His angels and His messengers. Whatever His angels and Messengers have learned we know it.”
أَبُو عَلِيٍّ الاشْعَرِيُّ عَنْ مُحَمَّدِ بْنِ عَبْدِ الْجَبَّارِ عَنْ مُحَمَّدِ بْنِ إِسْمَاعِيلَ عَنْ عَلِيِّ بْنِ النُّعْمَانِ عَنْ سُوَيْدٍ الْقَلاءِ عَنْ أَبِي أَيُّوبَ عَنْ أَبِي بَصِيرٍ عَنْ ابي جعفر قَالَ إِنَّ لله عَزَّ وَجَلَّ عِلْمَيْنِ عِلْمٌ لا يَعْلَمُهُ إِلا هُوَ وَعِلْمٌ عَلَّمَهُ مَلائِكَتَهُ وَرُسُلَهُ فَمَا عَلَّمَهُ مَلائِكَتَهُ وَرُسُلَهُ فَنَحْنُ نَعْلَمُهُ.
