What is the ruling on receiving two scholarships in Algeria, knowing that the law prohibits this, and that a portion of these funds has already been disbursed?

It is not permissible to resort to deception to receive two grants simultaneously if the law prohibits it, and this act must cease in the future. The amounts disbursed unlawfully must be returned, unless one is absolved of them, as they remain a debt until paid. A grant is a gift that requires adherence to the regulations of the granting authority, and you mentioned that the law prohibits receiving two grants simultaneously, so this must be adhered to.
