أَخْبَرَنَا عَبْدُ الرَّحْمَنِ بْنُ صَالِحٍ، حَدَّثَنَا ابْنُ الْمُبَارَكِ، عَنْ الْأَوْزَاعِيِّ، قَالَ: "مَا زَالَ هَذَا الْعِلْمُ عَزِيزًا يَتَلَاقَاهُ الرِّجَالُ حَتَّى وَقَعَ فِي الصُّحُفِ، فَحَمَلَهُ، أَوْ دَخَلَ فِيهِ غَيْرُ أَهْلِهِ".
Imam Awza'i, may Allah have mercy on him, said: This knowledge remained strong as long as it was acquired orally from people, but when it began to be written in books, then unqualified people started to take it up or enter into it.
