Chapter 21 | A believer is one who has seven characteristics
7-31 حدثنا محمد بن الحسن رضي الله عنه قال: حدثنا محمد بن يحيى العطار، عن محمد بن يحيى قال: حدثني أحمد بن محمد وغيره بإسناده رفعاه إلى أمير المؤمنين عليه السلام أنه قال: المؤمن من طاب مكسبه، وحسنت خليقته، وصحت سريرته، وأنفق الفضل من ماله، وأمسك الفضل من كلامه، وكفي الناس من شره وأنصف الناس من نفسه
7-31 Muhammad ibn al-Hassan - may God be pleased with him - narrated that Muhammad ibn Yahya al-Attar quoted Muhammad ibn Yahya, on the authority of Ahmad ibn Muhammad and others who linked it up through a chain of narrators to the Commander of the Faithful Imam Ali (MGB), “A believer is one whose business is legitimate; is good-tempered; has a good soul; gives charity from his excessive wealth; doesn’t talk a lot; the people are secure with him; and he treats others fairly.”
