Reference: al-Muntaqaa min Fataawa al-Fowzaan – Question No.164
Question: What is your opinion regarding a woman who leaves a copy of the Qur.aan beside her young child, intending by doing so his protection from the jinn whilst she is busy and he is alone?
Response: This is not permissible; that is because it is an insult to the Noble Qur.aan, and also because doing so [in this manner] has not been legislated.
