Hadith 1:

أَنَّ أَبَانَ بْنَ تَغْلِبَ قَالَ‌ غَدَوْتُ مِنْ مَنْزِلِي بِالْمَدِينَةِ وَ أَنَا أُرِيدُ أَبَا عَبْدِ اللَّهِ ع فَلَمَّا صِرْتُ بِالْبَابِ خَرَجَ عَلَيَّ قَوْمٌ مِنْ عِنْدِهِ لَمْ أَرَ قَوْماً أَحْسَنَ زِيّاً مِنْهُمْ وَ لَا أَحْسَنَ سِيمَاءَ مِنْهُمْ كَأَنَّ الطَّيْرَ عَلَى رُءُوسِهِمْ‌ ثُمَّ دَخَلْنَا عَلَى أَبِي عَبْدِ اللَّهِ ع فَجَعَلَ يُحَدِّثُنَا بِحَدِيثٍ فَخَرَجْنَا مِنْ عِنْدِهِ وَ قَدْ فَهِمَهُ خَمْسَةُ نَفَرٍ مِنَّا مُتَفَرِّقَ الْأَلْسُنِ مِنْهَا اللِّسَانُ الْعَرَبِيُّ وَ الْفَارِسِيُّ وَ النَّبَطِيُ‌ وَ الْحَبَشِيُّ وَ السَّقْلَبِيُ‌. فَقَالَ بَعْضُنَا لِبَعْضٍ مَا هَذَا الْحَدِيثُ الَّذِي حَدَّثَنَا بِهِ. فَقَالَ مَنْ لِسَانُهُ عَرَبِيٌّ حَدَّثَنَا كَذَا بِالْعَرَبِيَّةِ وَ قَالَ الْفَارِسِيُّ مَا فَهِمْتُ إِنَّمَا حَدَّثَ بِكَذَا وَ كَذَا بِالْفَارِسِيَّةِ وَ قَالَ الْحَبَشِيُّ مَا حَدَّثَنِي إِلَّا بِالْحَبَشِيَّةِ وَ قَالَ السَّقْلَبِيُّ مَا حَدَّثَنَا إِلَّا بِالسَّقْلَبِيَّةِ فَرَجَعُوا إِلَيْهِ فَأَخْبَرُوهُ. فَقَالَ ع الْحَدِيثُ وَاحِدٌ وَ لَكِنَّهُ فُسِّرَ لَكُمْ بِأَلْسِنَتِكُمْ‌

Narrated that Aban bin Taglib said,

"I went early morning from my house at in Medina to Abu Abd-Allah Imam Sadiq (عليه السلام). When I came to the door, a group came out to me from His presence, I did not recognize them and had not seen any people better dressed than them, nor of better appearance than them. It was as if there were birds upon their heads (i.e., calm, dignified).

Then we entered to see Abu Abd-Allah (عليه السلام). The Imam went on to narrate to us with a Hadeeth. We went out from His presence, and five (as per narration in Bihar it is 15) persons from us of difference languages had understood the hadith. The languages were Arabic, Persian, Nabatean, Ethiopian, and Slavic."

Then some of us said to one another, "What is this hadeeth that he told us?"

Then the one whose language was Arabic said, 'He narrated to me with such and such in Arabic.' And the Persian said, 'I did not understand. But rather, He narrated to me with such and such in Persian language'. And the Ethiopian said, 'He did not narrate to me except in Ethiopian language'. And the Slavic said, 'He did not narrate to us except in Slavic language'."

So they returned to the Imam and informed Him.

Imam (عليه السلام) said, “The Hadeeth is one, but it was explained to you all in your own languages."
