MUSLIM GROUPS AND AQEEDAH POSITION
BISMILLAHIR RAHMANIR RAHEEM
Just  ask an Aalim/hard core supporter of any group (in India most notably  Deobandi/Barelvi/Salafi(Ahle Hadith) a simple question.
Question. What is the difference between your group and other group??.
Answer:  The answer he will give that we have Aqeeda differences. He will say  that our group is on the Aqeeda of Ahle sunnat Wal Jamaat and obviously  the other one is deviated.As Aqeeda is most important for a muslim so  any further deliberation stops because it looks that they have basic  differences.
But the reality is NOT supporting that answer. It is a case of misprojection
Too understand the real picture Lets know some important facts.
1.    While  the differences of fiqh (Jurisprudence ) is right from the day of  Sahaba, and this became further evident with the four school  of  Fiqh,and later development of  Ahle Hadith.
2.    There was no difference in the matter of Aqeeda among Sahaba . 
3.    As  aqeeda matter has been described in detail in various Ayats of quran  and Ahadith of hazrat Muhammad Sallallahu Alaihi Wasallam. These six  articles of belief has been described in clear words in Quranic Ayats  and has been sum up in the Hadith of Jibraeel that is in Bukhari and  Muslim shareef both.
4.    And all the salfussalihin and Four great Imams and Muhaddithin were having no difference in the matter of Aqeeda. 
.     Schools of Aqeedah among present day Sunni Muslim
There are only two surviving schools of Aqeedah among mainstream muslims. They are  
 1.    Ashari and Maturidi School of Aqeedah
 2.    Salafi school
These are only the surviving school of Aqeeda among sunnis all over the world. 
  5.    The development of Ashari and Maturidi school  of Aqeeda was out of necessity and not out of fun. 
6.    Aqeeda  Schools came into existence to deal with the deviated philosophical  interpretation of quran and hadith and subsequent deviation that emerged  after 300 Hijri with the rise of Muatazilla under the patronage of  Mamoon and Muatasim of Abbasi Dynasty. 
8.    In matter of jurisprudence there are four school (hanfi,shafai,maliki,hanbli) plus Gair Muqallids but in Aqeeda only these two.
9.    The  groups (namely Deobandi,Barelvi,kerala Sunnis AP and Ek) belong to  Ashari/Maturidi School of Aqeedah while Ahle Hadith/kerala Mujahids are  of Salafi School.
10.                       Jamaat  Islami and Tablighi Jamaat are basically Dawah movement and in  principle do not involve in Aqeeda differences issue..(But it is  perception is that Tabligh is synonymous to Deoband and Jamaat Islami is  close to Ahle Hadith, but in reality this perception is not true.The  individual member of Tabligh and JI may be closer to these in his  personal capacity but on organization level they don’t have any  proximity to any group.
11.                       The difference of  Ashari/Maturidi  and Salafi are also not in principle.
Principle of both of these are muslim should believe the aqeeda as detailed in quran and Ahadith as explained by sahaba and great scholars and Imams of first few generation. and no philosophical and interpretational approach will be applied to explain it.
Both are dead against all the philosophical thought and logical interpretational approach of Muatazillah,Jehmiah and other Deviated group.

12.                       Most  of the differences that the different group claim between them are  actually not of Aqeeda matter.Rather based on some ijtahad/dispute over authenticity of a particular hadith.But in public these  differences are designated as Aqeeda differences.
13.                       They differ only in some details of certain points. (These will be elaborated in discussion)  
14.                       Some  of these differences are on those detail that were not considered  important enough to be discussed by sahabah and scholars of knowledge.  Sahabah asked from prophet detail of even small things of daily life if  these Aqeedah detail would have been important for deen surely they  would have asked,this sprit was followed by all the pious and  knowledgable scholars of Salfussaliheen.
e.g  One person came to Imam Malik (R.A) and asked What is the EXPLANATION of  Istawa Alal Arsh He replied ; Istawa is definite and kaifiat (detail) is not  known. After that he asked the questioner to be chased away from his  majlis/meeting and said he is spreading Fitnah.   (To be continued)
