و أما حق معاشر با تو اينست كه او را نفريبى، با او دغلى نكنى، به او دروغ نگوئى، غافلش نسازى، گولش نزنى و براى او كارشكنى نكنى مانند دشمنى كه براى طرف خود ملاحظه اى ندارد. اگر بتو اعتماد كرد هر چه توانى براى او بكوشى، و بدانى كه مغبون كردن كسى كه بتو اعتماد كرده مانند انجام ربا است.
And as for the right of your associate, you need not to deceive him and betray him and do not lie to him and do not fool him like a careless enemy who has no regards for the other side, and if he trusts you, do your best for him knowing that betraying someone who trusts you is like usury, and there is no power except in Allah.
