"Fight against your lower desires, overcome your anger, and oppose your bad habits. You will purify yourself, perfect your intellect, and you will indeed bring to completion the reward that is with your Lord." - Imam Ali (as)
Umar ibn al-Khattab: "If your brother mentions something to you in private, then walks away, it is an amaanah (trust) even if he didn't instruct you not to inform anyone." (Ibn Muflih’s Adaab Ash-Sharee’ah).
