أَخْبَرَنَا سَعِيدُ بْنُ عَامِرٍ، عَنْ إِسْمَاعِيل بْنِ إِبْرَاهِيمَ، عَنْ يُونُسَ، قَالَ: كَتَبَ إِلَيَّ مَيْمُونُ بْنُ مِهْرَانَ: "إِيَّاكَ وَالْخُصُومَةَ وَالْجِدَالَ فِي الدِّينِ، وَلَا تُجَادِلَنَّ عَالِمًا، وَلَا جَاهِلًا، أَمَّا الْعَالِمُ، فَإِنَّهُ يَخْزَنُ عَنْكَ عِلْمَهُ، وَلَا يُبَالِي مَا صَنَعْتَ، وَأَمَّا الْجَاهِلُ، فَإِنَّهُ يُخَشِّنُ بِصَدْرِكَ وَلَا يُطِيعُكَ".
Yunus (bin Ubaid) said that Maymun bin Mihran wrote to me: Avoid dispute and argumentation in religion, and do not quarrel with anyone, whether learned or ignorant. Do not quarrel with the learned, because he will withhold his knowledge from you and will not care about what you have done. And do not quarrel with the ignorant, because he will become angry with you and will abandon obeying you.
