A Letter From Maktubat-i Rabbani

The Great Islamic Scholar Hadrat Imam Rabbani states in the 234rd letter of the first volume of his book "Maktubat":

Every bid'at [1] holder has inferred wrong meanings from ayats [2] of Qur'an al-karim and hadith-i sharifs [3] with covered meanings. Our Prophet 'alaihis-salam' said, "He who gives a false interpretation to the Qur'an according to his own mind, thought and knowledge, and who writes made up interpretations [those opposed to the interpretations which the great men of religion have prepared after learning them from our Prophet and from his Ashab [4]] is a kafir (disbeliever)." We shouldn't buy or read the false books of interpretations published to make money by those who know nothing of salat [5] and iman (belief); we shouldn't believe their decorated advertisements.

[1] bid'at: (pl. bida') heresy; false, disliked belief or practice that did not exist in the four sources of Islam but which has been introduced later as an Islamic belief or 'ibada in expectation of thawab (blessings) ; heresy.
[2] ayat: A verse of al-Qur'an al-karim; al-ayat al-karima.
[3] hadith (sharif): i) a saying of the Prophet ('alaihi 's-salam).; al-Hadith ash-sharif: all the hadiths as a whole; ii) 'ilm al-hadith; iii) Books of the hadith ash-sharif. iv) Al-hadith al-qudsi, as-sahih, al-hasan: kinds of hadiths (for which, see Endless Bliss, II).
[4] As'hab-i kiram: (as-Sahabat al-kiram); the Companions of Rasulullah.
[6] salat: i) prayer; (with salam)= salawat; ii) ritual prayer of at least two rak'as; "namaz", in Persian; salat janaza: funeral prayer.
