Is it permissible to remove a copy of the Qur’an from the mosque due to the scarcity of worshippers and the abundance of Qur’anic copies within it?

The waqf (endowment) Qur'ans belonging to a mosque are not permissible for anyone to take for themselves or for others. It is permissible to transfer them to another mosque, provided that they are not being used in the first mosque and will be utilized in the mosque to which they are transferred.
