Is prayer valid if the mosque deviates 89 degrees from the Qibla, and must past prayers be repeated, and is it permissible to continue praying in this mosque given the current situation?

Deviation from the Qibla by 89 degrees is considered a significant deviation that invalidates the prayer, as it causes the worshiper to face the Qibla with their side, not their face. There is no argument in the hadith: "What is between the East and the West is a Qibla" for the people of Madinah, as it specifically applies to their direction. Furthermore, intentionally slight deviation invalidates the prayer according to some jurists, so what about a significant deviation?

The prayer of women in front of the Imam is not valid according to the majority of jurists, as one of the conditions for the validity of following the Imam is that the worshiper must not precede their Imam.

Those in charge of the mosque must rectify the deviation and change the direction of the mosque to align with the Qibla. They must also repeat the past prayers that were performed with this deviation.
