Is it permissible for women to pray the funeral prayer individually on the second floor if the deceased is on the first floor and they cannot follow the Imam?

There are three situations for praying over a deceased person: when the deceased is in front of the worshipper, when the deceased is absent (Salat al-Gha'ib - prayer for the absent), or at the grave after burial. The prayer over the deceased is not valid if the deceased is in one house and the worshipper is in another house without following an imam, because one of its conditions is the presence of the deceased before the worshipper. The bier must be directly in front of the worshipper, and the prayer is not valid if it is behind a wall. If women can follow the Imam while they are on the second floor by hearing his takbeers, their prayer is valid, otherwise it is not.
