3- Abstinence from those that are having false and incorrect thought

In order to have well and sound thinking, staying away from those that are having false and incorrect thinking is necessary.  By staying away from credulous people, you will protect yourself from their false and incorrect thinking, because ordinary people including the credulous people and those who are easy to be deceive are weak in terms of thinking.

The commander of the faithful (peace be upon him) said:  

Whoever is weak in thinking; to be quickly deceived is strong and obvious.[1]

Weakness in thinking make the possibility and preparedness of being deceived; therefore in the sense that the power of thinking of these types of people is little, imagination and illusion is very strong in them and base on this; they quickly accept the manifestation of other people.

So being defeated by imagination and illusion normally create state of acceptance in person; but thinking and reflecting are always after evidence and proof; meanwhile state of acceptance is in a situation whereby the conditions exist. In this respect, the holy household of the Prophet (peace be upon them) has prevented us from accompanying those that are weak in thinking so that their false and incorrect thinking should not transfer to us as a result of our staying together with them.
