 ١١ـ إِسْحَاقُ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ الاقْرَعِ قَالَ حَدَّثَنِي أَبُو حَمْزَةَ نُصَيْرٌ الْخَادِمُ قَالَ سَمِعْتُ أَبَا مُحَمَّدٍ غَيْرَ مَرَّةٍ يُكَلِّمُ غِلْمَانَهُ بِلُغَاتِهِمْ تُرْكٍ وَرُومٍ وَصَقَالِبَةَ فَتَعَجَّبْتُ مِنْ ذَلِكَ وَقُلْتُ هَذَا وُلِدَ بِالْمَدِينَةِ وَلَمْ يَظْهَرْ لاحَدٍ حَتَّى مَضَى أَبُو الْحَسَنِ (عَلَيْهِ السَّلام) وَلا رَآهُ أَحَدٌ فَكَيْفَ هَذَا أُحَدِّثُ نَفْسِي بِذَلِكَ فَأَقْبَلَ عَلَيَّ فَقَالَ إِنَّ الله تَبَارَكَ وَتَعَالَى بَيَّنَ حُجَّتَهُ مِنْ سَائِرِ خَلْقِهِ بِكُلِّ شَيْ‏ءٍ وَيُعْطِيهِ اللُّغَاتِ وَمَعْرِفَةَ الانْسَابِ وَالاجَالِ وَالْحَوَادِثِ وَلَوْ لا ذَلِكَ لَمْ يَكُنْ بَيْنَ الْحُجَّةِ وَالْمَحْجُوجِ فَرْقٌ.
 11. Ishaq has narrated from Ahmad ibn Muhammad al-Aqra‘ who has said that narrated to me abuhz Nasir al-Khadim the following. “I had heard many times that abu Muhammad  to each of his Roman, Turkish and Saqaliba slaves in their own languages. It was astonishing to me and I would think that he is born in al-Madina and has not exposed to anyone until abu al-Hassan passed away and no one saw him. How is this that he speaks such languages? I talking to myself that he came to me and said, “Allah, the Most High, the Most Holy, grants distinction to Leader with Divine Authority over the other creatures in all matters. He give them distinction in the matters of languages, knowledge of the genealogical issues, of the duration of lives and events. Without such distinctions there will be no difference between Leader with Divine Authority and others.”
