Is it permissible to dispose of borrowed games and amusements from friends, fearing they might distract them when returned to them?

You must return the permissible items you borrowed to their owners. Your fear of distracting them does not permit you to withhold these items from them, because Allah Almighty has commanded the return of trusts to their rightful owners, and because the Prophet, peace and blessings be upon him, said: "Return the trust to the one who entrusted you." However, if the items were impermissible, then refer to the specific fatwas regarding that.
