يَا بُنَيَّ اجْعَلْ نَفْسَكَ مِيزَاناً فِيمَا بَيْنَكَ وَبَيْنَ غَيْرِكَ، فَأَحْبِبْ لِغَيْرِكَ مَا تُحِبُّ لِنَفْسِكَ، وَاكْرَهْ لَهُ مَا تَكْرَهُ لَهَا، وَلَا تَظْلِمْ كَمَا لَا تُحِبُّ أَنْ تُظْلَمَ، وَأَحْسِنْ كَمَا تُحِبُّ أَنْ يُحْسَنَ إِلَيْكَ، وَاسْتَقْبِحْ مِنْ نَفْسِكَ مَا تَسْتَقْبِحُهُ مِنْ غَيْرِكَ، وَارْضَ مِنَ النَّاسِ بِمَا تَرْضَاهُ لَهُمْ مِنْ نَفْسِكَ، وَلَا تَقُلْ مَا لَا تَعْلَمُ وَإِنْ قَلَّ مَا تَعْلَمُ، وَلَا تَقُلْ مَا لَا تُحِبُّ أَنْ يُقَالَ لَكَ.
O my child, make yourself the measure (for dealings) between you and others. Thus, you should desire for others what you desire for yourself and hate for others what you hate for yourself. Do not oppress as you do not like to be oppressed. Do good to others as you would like good to be done to you. Regard bad for yourself whatever you regard bad for others. Accept that (treatment) from others which you would like others to accept from you. Do not talk about what you do not know even though what you know be very little. Do not say to others what you do not like to be said to you.
