The ruling on placing advertising boards in mosques, and the ruling on writing on the walls of the mosque

The questioner:
Also, our honorable Shaykh, may Allah benefit Islam and the Muslims through you and your knowledge. Abu Aishah asks: Some of the imams of the mosques place a board in the mosque to announce whatever new events occur in the neighborhood, such as the death of so-and-so, or an invitation to a lesson and dinner, or the wedding of so-and-so on such-and-such a day. He asks: What is the ruling on placing these advertising boards in the mosques?

The Shaykh:
It is not permissible to write in the mosques, place boards, or put up advertisements; because this distracts the worshippers. So, do not write on the walls of the mosques, and do not hang notices in the mosques, because this distracts the worshippers. Whoever wants to notify people of something should notify them by speech, not by writing. He should notify them by writing a letter or calling people with his tongue, saying, "So-and-so has a gathering and invites you to it," or "He has, for example, an occasion and invites you to it." There is no harm in that, but this should not be done by writing inside the mosque. However, if he writes that outside the mosque and hangs it on the walls outside the mosque, there is no harm. Yes.

The questioner:
Our Shaykh, may Allah reward you. Does the ruling differ if these boards are used to write Prophetic hadiths, and some jurisprudential rulings related to the rulings of mosques, or to alert the worshippers to the rulings of the Shari'ah?

The Shaykh:
It is not permissible to hang things in the mosques or to write on the walls of the mosque from the inside, whether Qur'anic verses, Prophetic hadiths, sermons, supplications, or anything else. There should be no writings in the mosques so that the Muslims can devote themselves to prayer, supplication, and the remembrance of Allah, without looking at these writings. Yes.
