What is the ruling on cursing children and invoking evil upon them in moments of anger, and is there any sin entailed therein?

Cursing children and supplicating against them is a reprehensible and forbidden act. An angry person is responsible for their actions unless they lose consciousness. The lack of intention to harm them does not justify supplicating against them. A Muslim is required to control themselves when angry. It is befitting to supplicate for children for guidance and success, for a parent's supplication for their child is answered.
