Is it permissible to dispose of a sum of money found at the university, an amount that was found a week ago, and no one has yet come forward to claim it after inquiries were made and contact information was left?

It is not permissible to benefit from found money until a year has passed since its discovery. The found item (Luqatah) must be publicly announced for a year, and if its owner does not appear after this period, then it is permissible to dispose of it.
