BismillairahmaaniraheemIn the light of the teachings of our Most Holiest Blessed Prophet Muhammad (sawaw) the following criteria is required for that sect to be acceptable.
That they follow the teachings of Quran and the Ahle Bayt (as) or Sunnah of them (in other words Sunnah of those who folowed the perfect examples of the Blessed Prophet (sawaw).
If we examine the most oldest sects which are the Ahle Sunna and Ahle Shia. Among the Ahle Sunna there have been countless walis and among the Shia's non !. The Ahle Sunna follows the way of the Ahle Bayt through their four main intellectual Imams of fiqh. Where as the Shias follow the liks of Kuluni Mufid Qummi Majilisi and call it following the 11 Imams.
Whats the main difference between the Shia Mujtahids such as Kuluni Mufid Qummi Majlisi and now Khomaini and Khomanai compared to the teachings of the 11 Imams well the first thing which is apparent is the lack of respect towards the Quran, Ahle Bayt, Sahaba, and the Blessed wives of the Holy Prophet (sawaw) The 11 Imams always respected them but the Shia Mujtahid have played foul and have even issued false allegations towards the Blessed Ahle Bayt (as).
Now lets examine if the the araba Imams of the Ahle Sunna differ from the teachings of the the Ahle Bayt (as) and here we do not find any major differences. The respect is there the ways of Sunna do not differ, no matam five prayer times followed length of beards, respect of the Holy Quran Sahaba Ahle Bayt and the wives of the Holy Prophet (sawaw) shared.
Most important the Friends of Allah (swt) are chosen among them not among the Shias,Deo,Wahabi, Salfi and others.
The sect that will enter Jannat (Paradise) will be the one with the most FRIENDS OF ALLAH (swt) among them ! NO DOUBT !
