A divorcee taking from her daughter's money

Q: I am a divorced woman and have a daughter who is four years old. Her father sends me some money every month to support our daughter. I would like to know if it is permissible for me to spend the money which the father sends to support his daughter every month on my personal matters or my family. Is it permissible for me to give some of the money in charity? If the answer is in the affirmative, who will get the reward of such charity? Please note that I live in my father's house with my brothers and sisters and some of whom are still young, so when I buy some items for my child, I buy some items for them as well. Is there any sin on me regarding such practice? (Part No. 21; Page No. 187

A: Originally, the money sent by the father as a Nafaqah (obligatory financial support) for his daughter only and then should be spent to supply her with provisions and clothing. If you are obliged to take some of this money, it will be permissible for you to take some of it according to your need. However, you should not give any of this money as charity.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
