In The Name of Allaah, The Most Merciful, The Bestower of Mercy.

Why Do Khawaarij And Raafidah Make Takfeer of One Another? Shaikhul Islaam Ibn Taymiyyah [may Allaah have mercy upon him] said, “The people of bidah [adherents of religious innovations]- such as the khawaarij – initiate a religious innovation, excommunicate the one who opposes them and declare lawful the shedding of his [i.e. opponent’s] blood. These people refute the religious innovations of each other, whilst he (i.e. the refuter) is also an innovator in religious affairs, so he refutes a religious innovation with another religious innovation, and falsehood with another falsehood. [Al-Majmoo 16/96]

Why Do The Khawaarij and Rawaafid Make Takfeer of The Upright Leaders of Guidance And Those Who Adhere to The Authentic Prophetic Path? Shaikhul Islaam Ibn Taymiyyah [may Allaah have mercy upon him] said, “The basis of the misguidance of these ones is their belief that the leaders of guidance and the main group of Muslim upon sound unity have exited the (confines) of justice and are misguided. This is the view of those who have abandoned the authentic Sunnah, such as the Raafidah and those similar to them. And that which they consider to be oppression, they hold that it is disbelief and then innovate rulings for it. These are the three stances of those who exit the Sunnah, such as the Harooriyyah [i.e. khawaarij], the raafidah [Shiites] and those similar to them. They isolate some of the fundamental principles of the Islamic Religion until they exit from it (completely), just like an arrow goes through a hunted game. [Majmoo 28/496]

These are some of the evil ones who nurture children upon falsehood and evil indeed is the affair of that one who calls to misguidance. Allaah [The Mighty and Majestic] said:

[إِنَّا نَحۡنُ نُحۡىِ ٱلۡمَوۡتَىٰ وَنَڪۡتُبُ مَا قَدَّمُواْ وَءَاثَـٰرَهُمۡۚ وَكُلَّ شَىۡءٍ أَحۡصَيۡنَـٰهُ فِىٓ إِمَامٍ۬ مُّبِينٍ۬ – Verily, We give life to the dead, and We record that which they send before (them), and their traces, and that which they leave behind], and all things We have recorded with numbers (as a record) in a Clear Book. [Surah Yaa Seen. Verse 12]

Imaam Al-Aloosee [may Allaah have mercy upon him] said: That which they left behind of good deeds, such as the knowledge they taught people, books they wrote, land they gave as endowment or a building they built in the path of Allaah and other good deeds; or sins, such as establishment of laws [legislation, rules, regulations etc] that are tantamount to oppression and transgression, or setting up principles amongst the people that are tantamount to evil and corruption, and the evil Funoon [i.e. haraam professions, crafts etc] which they initiated and were revived after them by the corrupt people. (1)

Imaam As-Sadi [may Allaah have mercy upon him] said: It is the good and evil outcomes about which they were the cause of its occurrence during their life time and after their death, and those deeds that emanated from their statements, deeds and circumstances. Every good performed by one of the people due to the knowledge of the servant, his teaching and advice, or through enjoying good and forbidding evil, or knowledge he transmitted to the learners, or in a book which is benefitted from during his life and after his death, or a good deed, such as Salaah, Zakaat, Sadaqah or kindness based on which he was followed, or built a masjid or a place which the people benefit from and what is similar, it will be from the good outcomes that are written for him, and likewise are the evil outcomes. The Prophet [peace and blessings of Allah be upon him] said, “Whoever starts a good thing [i.e. something other than bidah and sin] and is followed by others, he will have his own reward and a reward equal to that of those who follow him, without it detracting from their reward in any way. Whoever starts a bad thing [i.e. a bidah, sin or something that opposes Islaam] and is followed by others, will bear the burden of his own sin and a burden equal to that of those who follow him, without it detracting from their burden in any way”. [Reported by al-Tirmidhi, no. 2675]

This subject matter makes clear to you the lofty station of calling to the path of Allaah, guidance to His path through every means and path that leads to it; and the lowly status of the caller to evil and a leader in it, and that he is the most degraded human being, one who has committed the severest crime and the greatest sin.
