Is eating and drinking from the orphan care funds that the family receives, in addition to the salary of the employed son, considered consuming an orphan's wealth?

There is no harm in mixing the money donated for orphans with your own money and consuming from it, as long as it is not done with the intention of corruption, based on the Almighty's saying: "And they ask you concerning orphans. Say, 'Improvement for them is best. And if you mix with them, then they are your brothers. And Allah knows the corruptor from the reformer. And had Allah willed, He could have put you in difficulty. Indeed, Allah is Exalted in Might and Wise.'" This verse was revealed as a concession after Muslims used to separate the food and drink of orphans, which caused them hardship and led to the spoilage of food. And Allah knows who intends reform and who intends corruption.
