Level Three - The Wara' of the Muttaqin (Those who have Allah-Consciousness)...
Level Three - The Wara' of the Muttaqin (Those who have Allah-Consciousness): These people refrain from sinning, and also refrain from those things in which there is doubt and those things which are permitted (halal) however in which there is a possibility that they will be dragged towards the forbidden (haram) if they perform these acts. For example, a person who speaks little since he fears that if he begins to speak too much, he may unknowingly backbite another person.
In reality, this sort of person has entered into a mental state of: أَتْرُكُ مَا لاَ بَأْسَ بِهِ حَذَراً مِمَا بَأْسَ بِهِ.
“I will refrain from those things which there is no problem in performing with the fear that I may go towards those things which are problematic (in performing).” Level Four - The Wara' of the Siddiqin (Those who are the Truthful Ones): At this level, one turns his attention completely away from everything other than Allah (SwT) because of the fear that he may waste precious time of his life (on other than His Creator).
This person also turns his spiritual eyes away from everything other than Allah (SwT) and focuses all of his attention only on Him so that the time of his life is spent in looking towards the Creator. Truthfully, the most valuable possession of our lives is time, but unfortunately sometimes we waste it and are negligent (of Allah (SwT)).
Thus, the truthful ones realize that their level of Wara' is in relation to the time and how they spend it and are careful that they do not waste it in being negligent of Allah (SwT). Imam Ja'far b. Muhammad as-Sadiq (as) has said that the most precautious of people are the family of the Prophet and their followers (Shia) and that the minimum level that they (the Shia) must be at is the first level - meaning that the Shia must be fair and upright ('Adil) people and leaders for other people.
Thus, a Shia must not only be trying to save himself (from the hell fire), but he must also be striving to save others around him.
