(4) Ahmad bin Muhammad bin Sa’eed narrated from Abu Abdullah Ja’far bin Abdullah from al-Hasan bin Ali bin Fadhdhal from Safwan bin Yahya from Ishaq bin Ammar as-Sayrafi from Abdul A’la that Imam Abu Abdullah Ja’far bin Muhammad said: “Knowing this matter is not enough to prove your loyalty unless you keep it secret from those, who are not reliable. It suffices you to say what we have said and to be silent on what we have been silent on. If you tell of what we have said and submit to what we have kept silent, then you have believed in what we have believed in. Allah says: "And if they believe in the like of that which ye believe, then they are rightly guided." (2:137) Ali bin al-Husayn has said: “Tell people of what they know and do not burden them with that they cannot bear then you will lead them to avoid us.”
