A number of our people have narrated from Ahmad ibn Muhammad ibn Khalid from ‘Uthman ibn ‘Isa from Sama’a who has said the following: “I heard abu al-Hassan (a.s.) saying, ‘Do not consider a great deal of good deeds a great deal. Do not consider a little sin little; the little sins accumulate to become a great deal. Have fear of Allah in private so you can yield to justice against yourselves. Hurry up in obedience to Allah, be truthful in your words, keep the trust; it is for you.

Do not be involved in what is not lawful to you; it is against you.’” وثق - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (11/371))
