What is the ruling regarding the past prayers performed by the daughter facing the wrong direction due to ignorance or forgetfulness for a year and a half, and what must she do?

If a Muslim prays facing a direction other than the Qiblah, whether due to forgetfulness or negligence, and then becomes aware of their mistake, they must repeat the prayer, according to the consensus of scholars. This is because facing the Qiblah is a condition for the validity of prayer. It is essential to give due importance to prayer and to all conditions without which it is invalid, such as complete purification, covering the 'awrah, and facing the Qiblah. The girl must repeat the prayers she performed facing a direction other than the Qiblah after reaching puberty. If she does not know the exact number, she should pray what she believes will absolve her responsibility. She must also be careful to face the Qiblah in the future.
