Is it obligatory to repeat the ‘Isha prayer after menstruation ends if there are doubts about the validity of the ablution and the performance of the prayer before the onset of menstruation?

If you doubt the invalidation of your purity (tahara) during prayer, do not pay attention to this doubt; because the original state is the continuation of purity, and a person in prayer should not turn away [from prayer] until they hear a sound or find a smell. And if the doubt occurs after finishing the prayer, or you doubt the completion or deficiency of the prayer, do not pay attention to it; because doubt in an act of worship after completing it does not affect its validity. So, your prayer is valid, and you are not required to repeat it.
