Ruling 769

Someone who wants to perform prayers must make efforts to find out the direction of qibla to the extent that he attains certainty – or that which comes under the rule (ḥukm) of certainty, such as the testimony of two dutiful people, if their testimony is based on sensory perception and suchlike – about its direction. If he cannot, he must act in accordance with what he supposes to be the direction of qibla based on the position of the miḥrāb14 of a mosque, or the graves of believers, or by some other way. Even if he bases his supposition (ẓann) on the words of an immoral person or a disbeliever who knows the direction of qibla by employing scientific principles, it is sufficient.

14 This is a niche, chamber, or slab in a mosque that faces the direction of Mecca and where the imam usually stands for congregational prayers.
