By examination and verification of the "Tajweed Qur'an"
(wa-rattel-el-Qur'ana tartila) related to "DAR AL-MAARIFAH", it has been ascertained that it is in the Othmani style. The methodology adopted by the publishing house has been accurately applied after examining the passages written at the end of it, wherein the publisher explains everything relevant to the application of the idea of coloring ...)

(...The committee of the Noble Qur'an has examined this copy and found it correct in terms of calligraphy and vowelization, and that the idea of time and color coding is a unique and creative idea, and does not conflict with calligraphy and vowelization. It also helps the reader understand the Tajweed rules and their application by means of the codes set at the bottom of each page. The committee attests: That "DAR AL-MAARIFAH" has accurately applied its idea flawlessly.)

(Quoted from the report of the Revision Committee of Noble Qur'an approved on Sep. 6th 1999)
(...The committee recommends that there will not be more than one copy of the Noble Qur'an that applies the color-coding of the rules of Tajweed.)
