Ruling 866

The second condition: the place where obligatory prayers are performed must not move so vigorously that it would prevent the person performing prayers from standing and performing rukūʿ and sujūd normally; in fact, based on obligatory precaution, the movement must not prevent his body from being steady. If due to shortage of time or any other reason one is compelled to perform prayers in such a place – for example, in certain types of cars or on a ship or train – he must remain still and face qibla as much as possible. If the vehicle moves away from the direction of qibla, he must turn and face the qibla again; and if it is not possible to face qibla precisely, he must try to ensure that the difference is less than ninety degrees; and if this is not possible, he must face qibla at least while performing takbīrat al‐iḥrām; and if even this is not possible, it is not necessary for him to face qibla.
