Unity is based on the Book and the Sunnah and not bidah. We do not look for a common enemy and unite against him… because as soon as we overcome him, we will start to fight amongst ourselves.
And [remember] when Musa [Moses] said to his people: “Verily, Allah commands you that you slaughter a cow.” They said, “Do you make fun of us?” He said, “I take Allah’s Refuge from being among Al-Jahilun [the ignorants or the foolish].” [2:67]
That is because the Jaahil [i.e. an ignorant person] is that one who speaks with a speech that contains no benefit and he is that one who mocks at the people. As for the sensible person, he sees that one of the most blameworthy traits -which is rebuked by [sound] religion and intellect- is to mock at someone who is a human being like himself. And if he has been favoured over that other person, then this favour necessitates that he thanks Allaah and shows mercy to Allaah’s servants. Therefore, when Musa [alayhis-salaam] said this to them [i.e. I take Allaah’s Refuge from being among the ignorant], they knew that it [i.e. what he commanded them] was truth, so they said: [ادْعُ لَنَا رَبَّكَ يُبَيِّن لَّنَا مَا هِيَ -call upon your Lord for us that He may make plain to us what it is! [2:68)]

Verily, We give life to the dead, and We record that which they send before (them), and their traces, and all things We have recorded with numbers (as a record) in a Clear Book. [Soorah Yaaseen Aayah 12]
[Verily, We give life to the dead, and We record that which they send before (them)]- Meaning: their good and evil deeds. [And their traces]-Meaning: the evil and good deeds they left behind [in this worldly life after their departure from this worldly life], which are then followed by others [are also recorded]. [1] Those deeds that came into effect because of their statements, deeds and state of affairs. [2]

Ibn Abbaas [radiyallaahu-anhumaa] said: Do not sit with the people of desires [i.e. ahlul bidah], for indeed sitting with them will cause sickness to the hearts.
They are neither Qurraa [i.e. reciters of the Qur’aan who follow it as it should be followed] nor are they a people of astute understanding in the religion, nor are they scholars of Tafseer. By Allaah! If they were to be placed in charge over your affairs, they would [perpetrate] the deeds of Chosroes and Heracles amongst you.
And verily, this is my Straight Path, so follow it, and follow not [other] paths, for they will separate you away from His Path. This He has ordained for you that you may become Al-Muttaqun [the pious] [6:153]
Abu Nu’aym [rahimahullaah] reported with his chain of transmission from Mujaahid [rahimahullaah] regarding the statement of Allaah: [وَلَا تَتَّبِعُواْ ٱلسُّبُلَ فَتَفَرَّقَ بِكُمۡ عَن سَبِيلِهِ – And follow not [other] paths, for they will separate you away from His Path], that it means: [Do not follow] Bidah [i.e. innovations in religion] and Shubuhaat [i.e. affairs that are made to resemble truth but are falsehood in reality].

And all praises and thanks be to Allaah, there are scholars of the Sunnah and upright [scholars]. Allaah [Glorified be He and free is He from all imperfections] has not [left you in a state to have] a need of the evil scholars and the books of misguidance, whilst we have authentic books. Therefore, we hold onto the [upright scholars and authentic books] -neither go to the scholars of misguidance nor the innovators, nor to the books that are mixed [with falsehood]. All praises and thanks be to Allaah, we have good books and scholars, so we hold onto the scholars and the authentic books.
