Ruling on borrowing from the bequeathed one-third for charitable purposes

Question:
My father passed away two years ago, and he left me a will—may Allah have mercy on him—stipulating that I should manage the one-third of his estate designated for bequests. I took the money, and the amount was considerable. I used it to buy goods, and it yielded a profit, praise be to Allah. If I sell, the amount increases. I have started giving charity from it and providing for those in need. Likewise, if someone wants to borrow, I lend them from that money. As for myself, I borrow from it when I need to and then repay it. Is there any issue with this borrowing? Please inform me, may Allah reward you with good. Is it lawful or forbidden?

Answer:
This contains much good and benefit. In any case, this is a good deed, and her effort to develop it is commendable. Everything that benefits the deceased is good. If it is placed in real estate, it would be more stable, such as in a house, a shop, or date palms. One can purchase real estate, which would be safer and more stable. Otherwise, this is a good deed: buying goods with it, allowing it to grow, attending to the means of profit, and giving charity from it.
As for her borrowing, she should not borrow. She should not borrow from it; rather, she should preserve it and work to increase its growth and revenue, without borrowing from it.
If she wants some of the profit, she should consult the authority, or consult the court. The court will assign her a portion, such as half the profit, one-third, one-quarter, or something similar that the court deems appropriate.
