Spending from the money dedicated to build a Masjid on the workers

Q 1: The person supervising the Masjid (mosque) construction had some money that was collected from a group of pious people to be spent on the construction. He spent 700 Riyals of this money to slaughter an animal and provided Iftar (the fast-breaking meal) for the workers. Is this permissible or should he pay for this from his own money?

A: There is nothing wrong with you spending the stated sum of money, as it was for the benefit of the Masjid. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
