Is a woman's prayer valid if she prays sitting in the street or in a car to avoid missing the prayer, especially when mosques are unavailable, and is facing the Qiblah required in this situation even if the entire prayer is performed while sitting, and is it permissible to pray in restaurants that serve alcohol?

Standing is a pillar of prayer and is not waived except in case of inability. The absence of a mosque is not an excuse for abandoning it. Therefore, whoever prays sitting without an excuse, their prayer is invalid and they must make it up. However, if one fears harm, they may pray according to their ability. If there is sufficient time, one should delay the prayer until they reach home. Prayer in restaurants that serve alcohol is valid if no impurity is touched, but it is disliked.
