عثمان بن عيسى عن سماعة قال: سمعت أبا الحسن موسى عليه السلام يقول لا تستكثروا كثير الخير ولا تستقلوا قليل الذنوب فان قليل الذنوب تجتمع حتى يصير كثيرا وخافوا الله في السر والعلانية حتى تعطوا من أنفسكم النصف وسارعوا إلى طاعة الله واصدقوا الحديث وأدوا الأمانة فان ذلك لكم ولا تظلموا ولا تدخلوا فيما لا يحل لكم فإنما ذلك عليكم.
10.ʿUthmān ibn ʿĪsā narrated from Samāʿah who said, “I heard Abā alḤasan Mūsā  saying, ‘Do not consider [your] many good deeds as abundant, and do not consider [your] few sins as paltry, for verily sins that are few keep accumulating until they become many. And fear Allah in [both] private and public, until you behave in a fair manner [with others]. Hasten towards the obedience of Allah, be truthful in speech, and fulfil the trust [that is entrusted to you], for indeed this is for your own benefit. Do not oppress [anyone] and do not enter into that which is impermissible for you, as that is to your detriment.’”
