The Permanent Committee said after studying the issue:

“There is no blame in a student carrying his backpack which has the Mushaf in it, whether he carries it on his back or places it on the floor behind him or in front of him. This is because he does not intend to degrade it by doing that, especially if the Mushaf is inside a bag and not apparent. This is from that which is tolerated“.
