What should a girl do if the time for prayer has arrived while she is outside the home without ablution, and there is no suitable place for her to perform it, and she cannot return home before the time for the next prayer?

If the time for prayer arrives while one is outside the home, effort should be made to perform ablution (Wudu') and pray on time. It is permissible to perform Wudu' inside the bathroom, though it is better to avoid it. If Wudu' is difficult and there is enough time to return home, it is permissible to combine two prayers if they are among those that can be combined. However, if there is a fear that the prayer time will expire before performing Wudu', then one must perform Tayammum (definition) (dry ablution) and pray on time. Tayammum serves as a substitute for Wudu', as Allah Almighty says: "And if you are ill or on a journey or one of you comes from the place of relieving himself or you have contacted women and find no water, then seek clean earth and wipe over your faces and hands with it."
