The fountain head of Knowledge is Ala Muhammad 
2 Aḥadīth
A number of our people has narrated from Ahmad ibn Muhammad from ibn Mahbub who has said that Yahya ibn ‘Abdallah abu al-Hassan the companion of al-Daylam narrated to us and who has said the following. “Once I heard Ja‘far ibn Muhammad say while a group of people of Kufa was present before him, “It is very strange of the people. They have received their knowledge from the Messenger of Allah. They have followed such knowledge and found guidance but they think that his Ahl al-Bayt (members of his family) have not received his knowledge. We are his Ahl al-Bayt (members of his family) and his descendants. In our house Divine inspiration came down and from us knowledge came out to them. Do they think that they have learned and found guidance but we remained ignorant and lost. This, certainly, is not possible.”
عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ مَحْبُوبٍ قَالَ حَدَّثَنَا يَحْيَى بْنُ عَبْدِ الله أَبِي الْحَسَنِ صَاحِبُ الدَّيْلَمِ قَالَ سَمِعْتُ جَعْفَرَ بْنَ مُحَمَّدٍ (عَلَيْهما السَّلام) يَقُولُ وَعِنْدَهُ أُنَاسٌ مِنْ أَهْلِ الْكُوفَةِ عَجَباً لِلنَّاسِ أَنَّهُمْ أَخَذُوا عِلْمَهُمْ كُلَّهُ عَنْ رَسُولِ الله ﷺ فَعَمِلُوا بِهِ وَاهْتَدَوْا وَيَرَوْنَ أَنَّ أَهْلَ بَيْتِهِ لَمْ يَأْخُذُوا عِلْمَهُ وَنَحْنُ أَهْلُ بَيْتِهِ وَذُرِّيَّتُهُ فِي مَنَازِلِنَا نَزَلَ الْوَحْيُ وَمِنْ عِنْدِنَا خَرَجَ الْعِلْمُ إِلَيْهِمْ أَ فَيَرَوْنَ أَنَّهُمْ عَلِمُوا وَاهْتَدَوْا وَجَهِلْنَا نَحْنُ وَضَلَلْنَا إِنَّ هَذَا لَمُحَالٌ.
Ali ibn Muhammad ibn ‘Abdallah has narrated from Ibrahim ibn Ishaq al-Ahmar from ‘Abdallah ibn Hammad from Sabbah al-Muzanni from al-Harith ibn Husayra from al-Hakam ibn ‘Utayba who has said the following. “A man met al-Husayn ibn Ali at al-Tha‘laba on his way to Karbala. He came in his presence and offered Islamic greetings to him. Al-Husayn asked, “Where are you from?” He replied, “I am from Kufa.” The Imam said, “By Allah, O brethren from Kufa, if only I had a meeting with you in Madina, I could have shown you the marks of Jibril in and around our house and his coming with Divine message to my grandfather. O brethren from Kufa, how can it be true that we be the ones to make people quench their thirst for knowledge from us but they would learn and we remain ignorant. This can not happen.”
عَلِيُّ بْنُ مُحَمَّدِ بْنِ عَبْدِ الله عَنْ إِبْرَاهِيمَ بْنِ إِسْحَاقَ الاحْمَرِ عَنْ عَبْدِ الله بْنِ حَمَّادٍ عَنْ صَبَّاحٍ الْمُزَنِيِّ عَنِ الْحَارِثِ بْنِ حَصِيرَةَ عَنِ الْحَكَمِ بْنِ عُتَيْبَةَ قَالَ لَقِيَ رَجُلٌ الْحُسَيْنَ بن علي (عَلَيْهما السَّلام) بِالثَّعْلَبِيَّةِ وَهُوَ يُرِيدُ كَرْبَلاءَ فَدَخَلَ عَلَيْهِ فَسَلَّمَ عَلَيْهِ فَقَالَ لَهُ الْحُسَيْنُ مِنْ أَيِّ الْبِلادِ أَنْتَ قَالَ مِنْ أَهْلِ الْكُوفَةِ قَالَ أَمَا وَالله يَا أَخَا أَهْلِ الْكُوفَةِ لَوْ لَقِيتُكَ بِالْمَدِينَةِ لارَيْتُكَ أَثَرَ جَبْرَئِيلَ مِنْ دَارِنَا وَنُزُولِهِ بِالْوَحْيِ عَلَى جَدِّي يَا أَخَا أَهْلِ الْكُوفَةِ أَ فَمُسْتَقَى النَّاسِ الْعِلْمَ مِنْ عِنْدِنَا فَعَلِمُوا وَجَهِلْنَا هَذَا مَا لا يَكُونُ.
