I have younger brothers, and they do things that anger my mother, so she curses them. Is my mother sinful for cursing my brothers?

The questioner:
Our sister says: Honorable Shaykh, I have younger brothers, but they are mischievous and do certain things that anger my mother. When my mother gets angry, she curses them. I ask you, Honorable Shaykh, is my mother sinful for cursing my brothers? Please give us a ruling, may Allah reward you with good.

The Shaykh:
First, it is not permissible for children to anger their mother, because this is undutifulness to parents. Indeed, Allah said: . .
So these children must conduct themselves with the manners that Allah the Exalted commanded them to have with their mother and their father. However, if they do something that angers the mother or the father, the father must be patient and not curse his children, because the father is one whose supplication is answered. If he curses them, he fears that his supplication may be answered, and the children may be harmed by it, and the harm may even reach him. So he must be patient, endure, seek reward from Allah, and not curse his children. Yes.

The questioner:
Does it become a sin and a deprivation if the mother curses them, or...

The Shaykh:
If she curses them without a reason and without a justification, she is sinful, because this is transgression, because this is transgression in supplication. But if it is for a reason, it is permissible, though it is better to leave it. Yes.
