It means following and accepting the word of another so blindly without any regard as to whether or not what he is saying is actually a part of the true religion or not. Allah has extreme dislike for the one who follows others so blindly and never tries to gain the marifat (recognition) of the religion himself. It is wajib (compulsory) upon everyone to continuously keep trying to gain as much knowledge as one possibly can regarding the religion.

Without knowledge neither will your belief nor your good deeds be of any benefit to you. As Masoom (as) says, "Be knowledgeable or try to gain knowledge, but do not follow others blindly" (Mazan ul Hikmat 8th Volume page no 431). One who does not recognize his religion and simply follows others blindly, then that person will certainly be excluded from the true religion.

Ghaybat e Nomania page no 22 and Mazan ul Hikmat 8t h Volume page no 476: Imam Jafar Sadiq (as) says, "Anyone who will enter into the religion through others, he will be taken out of the religion by those same who entered him into the religion. Anyone who will enter into the religion through Book and Sunnah, the mountains will move before he will be removed from the religion." These are a few of the points which we had briefly wanted to mention.

When you will begin to study, you will slowly begin to understand everything. InshaAllah. Marifat (recognition) The meaning of marifat is to recognize one by those attributes which only he possesses and no other has. For example, when we wish to gain the marifat of RasoolAllah (saw), we do this through His attribute "The Seal of all Prophets" because RasoolAllah (saw) is the only one who was given the attribute of "Seal of all Prophets" and it has never been given by Allah to any other person.

Likewise, regarding the marifat of all Masoomeen (as) you must recognize each by those attributes which are associated with only that individual Masoom (as). Tauheed will also be recognized in the same way. Marifat of Tauheed (recognition of Oneness) It is quite clear that we will gain the marifat of Allah through His attributes because it is impossible to gain His marifat through His zaat (essence). You cannot even recognize an ant by his zaat. We will also recognize it through its attributes.

So it is absolutely impossible to recognize Allah through His essence. We will recognize Allah through those attributes which are apparent (zahir). No one can be recognized through his hidden (batin) attributes.
