The wise Muslim woman does not pray against her own children, heeding the words of the Prophet (PBUH) who forbade such prayers lest they be offered at a time when prayers are answered. This was stated in the lengthy hadith narrated by Jabir in which the Prophet (PBUH) said:
"Do not pray against yourselves, or against your children, or against your wealth, in case you say such words at a time when Allah (SWT) will answer your prayer."21
Praying against one's own children is not a good habit. No mother does so at a time of anger, but she will regret it later on after she has calmed down. I do not think that a mother who has truly sought the guidance of Islam would lose her mind and her equilibrium to such an extent that she would pray against her own children, no matter what they did. Such a woman would not allow herself to indulge in something that is done only by foolish, hot-tempered women.
