Things which exclude one from the Religion
It has been proven from the sayings of Imam Jafar Sadiq (as) that it is compulsory for man to know those things which will exclude him from the religion. Here we shall point out a few of those things:
1. It has been clarified from our above words that the purpose of religion is to love Ahlul Bayt (as). Then without doubt the first thing which will immediately exclude one from the religion is the hatred of Ahlul Bayt (as) or the love of Their enemies. Attention is that which keeps the love alive. Negligence is that which destroys the love. So being negligent in the love of Ahlul Bayt (as) is included in those things which will exclude you from the religion.
Quran has clearly ordered us to perform muwaddah. As Allah says "O'Prophet! Say! I do not ask you for any reward for My prophet hood except the love of My nearest kin."
Muwaddah of Ahlul Bayt (as) is wajib (compulsory) because this is the reward of prophet hood, and without paying prophet hood its reward no one can enter into the religion. Therefore being negligent in the muwaddah of Ahlul Bayt (as) will without doubt exclude one from the religion. You must be very careful and be very aware of this extremely important matter. Even having some minor negligence in the muwaddah of Ahlul Bayt (as) can destroy your whole iman (faith).
We have spoken in great detail on this topic in our book Kashaful Muwaddah. Here we wish to say something that is off topic but will be of great benefit to you. All shia and sunni translators translate the word "qarba" (near kin singular form) as "qurba" which is absolutely wrong.
I have no idea where they get this translation from because in Arabic the word "qurba" is used for relatives (more than one). Qurba is plural while qarba is singular. In Quran Allah uses the word "qarba" which is feminine. For example the word "kabeer", it means great. Its superlative is "Akbar" which means the greatest. However akbar is masculine.
Therefore when you see the term "akbar" it is referring to the greatest "man". Its feminine will be "kubra" which will mean the greatest "woman". Likewise there is a word "sagheer" which means young. Its superlative is "Asghar" which means the youngest. Asghar is masculine. So akbar means youngest "man". Its feminine is sughra which means youngest "woman".
The superlative of the word kareeb (near) is "Akrab" (nearest). Akrab is masculine. Its feminine will be karba which means the nearest "woman" which is Syeda Fatima Zahra (sa). This is why Allah ordered us to love those who are associated with Syeda (sa) (qaraba).
2. The second thing which will exclude one from the religion is to decrease or increase those who are considered as Aimmah Masoomeen (as). This is an extremely important issue. However people do not ever give any importance to this issue.
We must be very careful and not shrug our responsibility regarding this very sensitive issue. Imam is that sacred term which countless shia have sacrificed themselves in order to protect the honor and dignity of. Shia have never ever used this term for a non Masoom. However nowadays simpleton shia have begun allowing any non Masoom to use this title for themselves in the name of "unity" with other muslims.
Non shia have intentionally used this term in order to destroy the importance of the title of "Imam" because imamate is not included in their usool e deen. However even though shia know the importance of the title of Imam, suddenly out of ignorance and without any fear of Allah, they have begun using this word for any non Masoom the same way as non shia. We shall tell you what an "Imam" is and what is the importance of "Imam" to Allah.
Sura Tawba ayah 36: "Lo! the number of the months with Allah is twelve months by Allah's ordinance in the day that He created the heavens and the earth. Four of them are sacred: that is the right religion"
In this ayah Allah is telling us that the 12 months are the true religion. In Umda tul Matalib First Edition page no 239, Imam Jafar Sadiq (as) said, "These 12 months are the 12 Imams (as)." You must ponder upon this point that Allah did not declare His tauheed as the true religion nor did He declare the prophet hood of RasoolAllah (saw) as the true religion.
He declared the number of 12 Imams (as) as the true religion. Now you must realize that how greatly Allah wishes to protect the number of 12. Including another or excluding one of those whom Allah has included in the 12 is the same as if you have destroyed the whole religion. Therefore anyone who excludes even just one of those 12 or includes even just one other with Them, then most certainly he becomes excluded from the religion because the 12 Imams (as) are the true religion.
3. The third thing which can exclude one from the religion is personality worshipping. 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.
