2ـ 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 (عَلَيْهِ السَّلام) مِنْ أَيِّ الْبِلادِ أَنْتَ قَالَ مِنْ أَهْلِ الْكُوفَةِ قَالَ أَمَا وَالله يَا أَخَا أَهْلِ الْكُوفَةِ لَوْ لَقِيتُكَ بِالْمَدِينَةِ لارَيْتُكَ أَثَرَ جَبْرَئِيلَ (عَلَيْهِ السَّلام) مِنْ دَارِنَا وَنُزُولِهِ بِالْوَحْيِ عَلَى جَدِّي يَا أَخَا أَهْلِ الْكُوفَةِ أَ فَمُسْتَقَى النَّاسِ الْعِلْمَ مِنْ عِنْدِنَا فَعَلِمُوا وَجَهِلْنَا هَذَا مَا لا يَكُونُ.
2. 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 عليه السلام at al-Tha‘laba on his way to Karbala. He came in his presence and offered Islamic greetings to him. Al-Husayn عليه السلام asked, “Where are you from?” He replied, “I am from Kufa.” The Imam عليه السلام 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.”
