Facing the Qiblah.
Machine translationRead the Arabic original
The Shaykh : And among that is also that a person faces the Qiblah, and facing the Qiblah is a condition for the validity of the prayer, due to the saying of Allah (Blessed and Exalted is He): [Al-Baqarah 2:150] And on this basis, if a person stays in a house as a guest of his companion, or stays in a house by rent or by purchase, and then prays in this house and it turns out that he prayed in a direction other than the Qiblah, it is obligatory for him to do what? Repeat the prayer, because he prayed in a direction other than the Qiblah, and facing the Qiblah is necessary.
