حَدَّثَنَا مِنْجَابُ بْنُ الْحَارِثِ التَّمِيمِيُّ، أَخْبَرَنَا ابْنُ مُسْهِرٍ، ح وَحَدَّثَنَا إِسْحَاقُ بْنُ،
 إِبْرَاهِيمَ الْحَنْظَلِيُّ أَخْبَرَنَا عِيسَى بْنُ يُونُسَ، كِلاَهُمَا عَنِ الأَعْمَشِ، بِهَذَا الإِسْنَادِ ‏.‏ وَلَمْ يَذْكُرْ
 فِي حَدِيثِ عِيسَى ‏"‏ وَيَتَحَرَّى الصِّدْقَ وَيَتَحَرَّى الْكَذِبَ ‏"‏ ‏.‏ وَفِي حَدِيثِ ابْنِ مُسْهِرٍ ‏"‏ حَتَّى
 يَكْتُبَهُ اللَّهُ ‏"‏ ‏.‏
