21. A number of our people have narrated from Sahl ibn Ziyad from Ali ibn Asbat from abu al-Hassan al-Rida عليه السلام who has said the following: “Amir al-Mu’minin, Ali ibn abu Talib عليه السلام has said, ‘Do not show your teeth (smile) if you have committed disgraceful sins. Do not feel safe from misfortunes if you have performed evil deeds.’”
