٢٠ـ عَلِيُّ بْنُ مُحَمَّدٍ عَنْ صَالِحِ بْنِ أَبِي حَمَّادٍ عَنِ الْحَجَّالِ عَمَّنْ ذَكَرَهُ عَنْ أَحَدِهِمَا (عَلَيهِما السَّلام) قَالَ سَأَلْتُهُ عَنْ قَوْلِ الله عَزَّ وَجَلَّ بِلِسانٍ عَرَبِيٍّ مُبِينٍ قَالَ يُبِينُ الألْسُنَ وَلا تُبِينُهُ الألْسُنُ.
20. Ali ibn Muhammad has narrated from Salih ibn abu Hammad from al-Hajjal from those whom he has mentioned (in his book) who has said the following: “Once I asked one of the two Imam  about the words of Allah, the Most Majestic, the Most Holy: ‘It has been revealed in plain Arabic.’ (26:195) The Imam said, ‘It (the Holy Quran) explains the languages but the languages do not explain it.’”
