Permissibility of a widow spending from her children's allotted money on them

Q: I am an old widow. The pension of my dead husband is divided equally among me, a 22-year old daughter, and a 16-year-old son. Each receives 500 Riyals. Though their elder brother receives a salary of 3,000 Riyals, they are insufficient to provide for his wife and children. Now, may I spend from the children's share of pension on meeting the house needs? I sometimes have to borrow money to meet these needs instead of taking their money as they are orphans.

A: It is permissible for you to spend from the share of the children to meet your needs and theirs and the needs of the house as required. (Part No. 21; Page No. 178) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
