What is the ruling on placing posters containing Ramadan hadiths on the walls of the mosque to renew intentions, and what is the ruling on decorating the mosque with verses?

Placing posters that contain verses and hadiths in a place where they will not be dishonored and will not distract worshippers is a form of calling to Allah, and the one who does so will be rewarded. This is not considered imitation of innovators; rather, it is in accordance with the Sunnah, as the Prophet, peace and blessings be upon him, used to give glad tidings to his companions about the arrival of Ramadan, and this is the origin of people congratulating each other on it. As for decorating the mosque with Quranic verses or ornamenting its walls, the jurists have stipulated that it is disliked because it falls under the prohibition of ornamenting mosques.
