أَخْبَرَنَا سَعِيدُ بْنُ عَامِرٍ عَنْ إِسْمَعِيلَ بْنِ إِبْرَاهِيمَ عَنْ يُونُسَ قَالَ كَتَبَ إِلَيَّ مَيْمُونُ بْنُ مِهْرَانَ إِيَّاكَ وَالْخُصُومَةَ وَالْجِدَالَ فِي الدِّينِ لَا تُجَادِلَنَّ عَالِمًا وَلَا جَاهِلًا أَمَّا الْعَالِمُ فَإِنَّهُ يَخْزُنُ عَنْكَ عِلْمَهُ وَلَا يُبَالِي مَا صَنَعْتَ وَأَمَّا الْجَاهِلُ فَإِنَّهُ يُخَشِّنُ بِصَدْرِكَ وَلَا يُطِيعُكَ

Narrated to us [Sa'id bin 'Amir] from [Isma'il bin Ibrahim] from [Yunus] he said: "[Maimun bin Mihran] said to me: 'Avoid quarreling and disputing in religion. Do not argue with those who know and those who are ignorant. As for those who know, indeed he keeps his knowledge from you and he does not care about anything you do. On the other hand, the fool hurts you and disobeys you.' ".
