Issue 395: The Quiblah is the Holy Ka'bah which is situated in Mecca, and one must offer their prayers facing it. However, one who is far from it, it would suffice if they stand in such a direction that any observer would say they are praying facing the Quiblah. This also applies to other acts which must be performed facing the Quiblah, like slaughtering the animals.

Issue 396: One, who is offering their obligatory prayers in a standing position, must stand in such a direction that people would say they are facing the Quiblah.

Issue 397: One may offer the recommended prayers while walking or riding, and they do not need to face the Quiblah in such cases.

Issue 398: If one does not have any means of determining the Quiblah, or in spite of their efforts, they cannot guess the direction of the Quiblah, as a recommended precaution, they should offer the same prayers four times, each time facing one of the four directions, although they are allowed to offer their prayers once in any direction.

Issue 399: One, who is not certain about the direction of the Quiblah, must act upon their calculated guess as to which direction it is if they want to do things other than prayers which must be done facing the Quiblah such as slaughtering an animal, and if they cannot make a guess, they are allowed to act in any direction and it will be valid.

Q400: To what extent does deviation from the direction of the Quiblah invalidate prayers?

A: If one deviates from the direction of the Quiblah intentionally, their prayers will absolutely be void. If after investigation and calculation, one determines the Quiblah, but later they realize that they have deviated from the direction of the holy Quiblah, it does not matter.

Q401: What must a person do about the Quiblah if they want to offer their prayer on a plane or a ship whose position is always changing?

A: As long as one can even guess the direction of the Quiblah, they must keep the Quiblah by turning towards it silently and slowly while the plane or ship is changing its position, but if they cannot determine the Quiblah, it will not be necessary to face the Quiblah and they can pray in any direction.
