Being pious
Avoiding from guilt, having virtue and avoiding from doubts and disapproved deeds is called being pious. To save us, we should pay attention to avoid the disapproved deeds and to do the recommended things. Recommended things strengthens doing obligatory rules, and avoiding disapproved deeds can help to avoid guilt and taboos.
Imam sadiq said: Everyone who wants to be Imam Mahdi’s companion should avoid from doubts plus abandoning committing sins. In fact, they should avoid doing anything which contains uncertainty (in being a good deed or a wrong one) both based on etiquette and wisdom.”
Avoiding doubts can make people and their Imam look like each other.
