Is it permissible to allocate a portion of the income of an academy that teaches the Holy Quran and the Arabic language to non-Arabs to charitable organizations, at the expense of not increasing the wages of its employees, who believe they are more deserving of this increase?

If the questioner's employment contract stipulates a specific wage, then she is not entitled to anything beyond that, as what is considered is the fulfillment of the agreed-upon wage. However, if the association's management allocates a portion of its income to associations or charitable works, then there is no objection to disbursing this portion to employees who fit this description, thereby achieving the charitable purpose of the donation.
