وَأمّــــــا حَقُّ الخَلِيطِ فَأَنْ لا تَغُرَّهُ ولا تَغُشَّـهُ ولا تُكَذِبَهُ ولا تُغَفِّلَهُ ولا تَخــــــــدَعَهُ ولا تَعمَلْ فِي انتِقَـــاضِهِ عَمَلَ الْعَدُوِّ الَّذِي لا يُبقِي عَلَى صَـــاحِبهِ وَإنِ اطْمَأَنَّ إلَيكَ اسْتَقْصَيتَ لَهُ عَلَى نفْسِـكَ وَعَلِمْتَ أَنَّ غَبْنَ الْمُسْتَرْسِلِ رِِبًا. ولا قُوَّةَ إلا باللهِ.
And the right of the associate is that you should not mislead, or cheat him, lie to him or fool him, and you should not trick him. And you should not treat him as an enemy does -who
alienates all his friends. If he trusts you, you should be very careful of yourself for his sake, and realize that cheating the intimate ones is like usury. And there is no power but in
God.
