Is it permissible to take old Mushafs of the Shumarli print from some mosques and place them in other mosques and Quran memorization centers that do not have this print, provided that new Mushafs are purchased and placed in their stead?

The questioner is advised to learn to read from all copies of the Qur'an (Masahif). Copies of the Qur'an are often endowed in mosques for reading, and they may be specifically intended for congregants in the mosques where they are placed. The rule concerning endowments (waqf) is that they must be used for the purpose specified by the endower, whether explicitly or implicitly. If it is known that the one who endowed the copies of the Qur'an did not differentiate between their reading in any mosque, then there is no impediment to moving them. However, if it is known that they were specifically designated for the mosque they are in, or if there is doubt about this, then it is not permissible to move them as long as they can still be utilized.
