What is the ruling on a woman leading two girls in prayer, one of whom is wearing trousers and the other has an uncovered foot?

The preponderant opinion is the permissibility of a woman leading other women in prayer, whether it is an obligatory prayer or a supererogatory one. A woman's 'awrah (parts that must be covered) in prayer is her entire body except for her face and hands. Her clothing must not be transparent, and it is disliked for it to be tight. As for a woman praying without covering her feet, this invalidates the prayer according to the preponderant opinion, because they are part of her 'awrah.
