The ruling on writing Qur'anic verses on walls, on the covering of the Ka'bah, and elsewhere?

Question : The questioner says: You said yesterday that writing Qur'anic verses and hanging them on walls is a religious innovation (bid'ah). What is your opinion, Honorable Shaykh, about what is written on the Sacred Ka'bah, the rest of the walls of the Sacred Precinct, and the ceilings of the Sacred Mosque, in the form of Qur'anic verses and the names of Allah (Mighty and Majestic)?

Answer : In our previous statement, we did not make any exception, and the implementation is left to others.
