Putting up Verses of the Qur'an and Sayings of the Messenger of Allâh ﷺ
Question :
Some people say that hanging up chapters (such as Ya Sin) or verses (such as Ayat Al-Kursi) of the Qur'an is unlawful; however, these verses and chapters are only put up because of their superiority and because of their virtues. Noble Shaykh, please clarify the ruling regarding this? And may Allah Almighty reward you well.
Answer:
For purposes of reminding and for purposes of admonition, it is permissible to put up Hadiths or verses and chapters of the Qur'an, even though some present-day scholars deem this act to be forbidden. However, the room wherein they are put up such as a living room or office should be clean and pure.
But if verses are put up for protection from jinn, from the evil eye, or from some other form of evil, then based on this intention, hanging up verses is forbidden, because there is no basis in the Shari'ah for doing such things. And Allah is the Grantor of success.
