[2/79] al-Khisal: In  the ‘Four Hundred’ Narration: the commander of the faithful عليه السلام said: Interact with the people with that which they know and leave them be as to that which they do not know, and do not impose (empower) them upon yourselves and us, our affair is hard (in of itself) and deemed hard (by others) – no one can bear it except an angel brought-near or a prophet sent or a slave whose heart has been tried for faith by Allāh.

[2/79] الخصال: في الحديث الأربعمائة قال أمير المؤمنين عليه السلام: خالطوا الناس بما يعرفون ودعوهم مما ينكرون، ولا تحملوهم على أنفسكم وعلينا، إن أمرنا صعب مستصعب لا يحتمله إلا ملك مقرب أو نبي مرسل أو عبد قد امتحن الله قلبه للإيمان
