علي بن النعمان عن ابن مسكان عن داود فن فرقد عن أبي شيبة الزهري عن أحدهما عليهما السلام أنه قال: ويل لمن لا يدين الله بالامر بالمعروف والنهى عن المنكر قال: ومن قال: لا إله إلا الله فلن يلج ملكوت السماء حتى يتم قوله بعمل صالح ولا دين لمن دان الله بغير امام عادل ولا دين لمن دان الله بطاعة ظالم وقال: كل قوم ألهاهم التكاثر حتى زار والمقابر قال ومن أحسن ولم يسئ خير ممن أحسن وأساء ومن أحسن وأساء خير ممن أساء ولم يحسن وقال: الوقوف عند الشبهة خير من الاقتحام في الهلكة.
18.ʿAlī ibn al-Nuʿmān narrated from Ibn Muskān, from Dāwūd ibn Farqad, from Abū Shaybah al-Zuhrī, from one of the two [Imams]  who said, “Woe be to the one who does not obey Allah through enjoining good and forbidding evil.” He [further] said, “Whoever says ‘There is no god but Allah’ will never go through the heavenly realms until his statement is complemented with righteous action. And one who submits to Allah without following a just Imām has no religion; and one who submits to Allah yet obeys an unjust person has no religion.” He [also] said, “All communities were deluded by seeking more [of this world than others], until they visited the graves.” He [further] said, “One who does good and does not sin is better than one who does good and [also] sins. And one who does good and sins is better than one who [only] sins and does no good.” And he said, “Stopping when in doubt is better than plunging into destruction.”
