Therefore, all these books that consist of opposition to the Sunnah have no permission to be written. Rather, they only have permission to be erased and destroyed, for there is not anything more harmful to the ummah than these books. The Sahaabah RAA burned all the copies of the mus-haf that opposed the mus-haf of 'Uthmaan RAA out of fear that differing would spread amongst the ummah (if they didn't do so). So how would it be if they were to see the books of today that cause disunity and division amongst the ummah!?" [22]

Then Ibn Al-Qayyim (ra) said:

"The objective is for these books, that contain lies and innovations, to be annihilated and destroyed. Destroying these books takes more precedence over destroying musical instruments and alcoholic containers, since their harm is much greater than the harm caused by these (latter) things. And there is no insurance to be paid for their loss, just as there is no insurance for breaking the vessels in which alcohol is drunk out of." [23]

Imaam Adh-Dhahabee (ra) said:

"Sa'eed Ibn 'Amr Al-Barda'ee said: ‘I witnessed Abu Zur'ah when he was asked concerning Al-Haarith Al-Muhaasibee and his books. And he responded to the questioner by saying: 'Beware of these books for these are books of innovation and misguidance! Stick to the narrations for indeed you will find in them that which is sufficient for you.’ Then it was said to him: ‘There is an admonition for us in these books.’ So he responded: ‘Whosoever does not receive admonition from the Qur’aan, then he will not receive any admonition from these books! Has it reached you that Sufyaan or Maalik or Al-Awzaa’ee wrote these types of books on false delusions and misgivings? How quick people are to rush to innovations!’

Al-Haarith died in the year 243 after Hijrah. So where are the likes of Al-Haarith, now? And how would it be if Abu Zur’ah (ra) were to see the books that were written in later times, such as Quwat-ul-Quloob (Strength of the hearts) of Abu Taalib?! And where are the likes of Quwat-ul-Quloob, now?!? How would it be if he were to see Bahjat-ul-Asraar (The splendors of the hidden dimensions) of Ibn Juhdam or Haqaa’iq-ut-Tafseer (The real/hidden meanings of the Qur’aan) of As-Sulamee?! He would go completely out of his mind!! How would it be if he were to see the books of Abu Haamid At-Toosee (i.e. Al-Ghazaalee), for that matter, due to the large amount of fabricated narrations found in Ihyaa ‘Uloom-ud-Deen (Reviving the Sciences of the Religion)?! How would it be if he were to see Al-Ghunyah of Shaikh ‘Abd-ul-Qaadir (Al-Jilani)?! How would it be if he were to see Fusoos Al-Hikam (The Segments of Wisdom) and Al-Fatoohaat Al-Makkiyah ?! [24]
