Rules of Qibla
784. Our Qibla is the holy Ka'bah, which is situated in Makkah, and one should offer one's prayers facing it. However, a person who is far, would stand in such a manner that people would say that he is praying facing the Qibla, and that would suffice. This also applies to other acts which should be performed facing the Qibla like, while slaughtering an animal etc.
785. A person offering obligatory prayers while standing should have his chest and stomach facing the Qibla, and his face should not digress from Qibla, and the recommended precaution is that the toes of his feet should also be facing Qibla.
786. If a person offers prayers while sitting, it is necessary that his face, chest and stomach face the Qibla.
787. If a person cannot offer prayers in the sitting posture, he should lie on the right hand side in such a manner that the front part of the body would face the Qibla. And if that is not possible, he should lie on the left hand side in such a manner that the front part of his body would face the Qibla. And if even that is not possible, he should lie on his back in such a manner, that the sole of his feet face the Qibla.
788. Namaz-e-Ihtiyat, and forgotten Sajdah, and forgotten tashahhud should all be offered facing the Qibla, and on the basis of recommended precaution, Sajda-e-Sahv should also be offered facing the Qibla.
789. A Mustahab namaz can be offered while one is walking, or riding, and if a person offers Mustahab prayers in these two conditions, it is not necessary that he should be facing the Qibla.
790. A person who wishes to offer prayers, should make efforts to ascertain the direction of Qibla, and for that, he has to either be absolutely sure, or acquire such information as may amount to certainty, like testimony of two reliable persons. If that is not possible, he should form an idea from the Niche (Mehrab) of the Masjid or from the graves of the Muslims, or by other ways, and act accordingly. In fact, if a non-Muslim who can determine Qibla by scientific method, indicates Qibla satisfactorily, he can be relied upon.
791. If a person, who has a mere surmise about Qibla, and is in a position to have a better idea, he should not act on that guess work. For example, if a guest has an idea about the direction of Qibla on the statement of the owner of the house, but feels that he can acquire a firmer knowledge about Qibla by some means, he should not act on his host's words.
792. If a person does not possess any means of determining the direction of Qibla, or in spite of his efforts, he cannot form an idea about it, it will be sufficient for him to offer his prayers facing any direction. And the recommended precaution is that, if he has sufficient time at his disposal, he should offer the same prayers 4 times, each time facing every one of the four directions.
793. If a person is sure or guesses that Qibla is on one of the two directions, he should offer prayers facing both.
794. If a person has to offer prayers facing a few direction, and wants to offer two prayers like Zuhr prayers and Asr prayers, which should be offered one after the other, the recommended precaution is that he should offer the first namaz facing those few directions, and then commence the second prayers.
795. If a person who is not certain about the direction of Qibla, wishes to perform acts other than namaz, which should be done facing the Qibla like, slaughtering an animal, he should act according to his surmise about the direction of Qibla , and if that does not seem possible, then performing the act facing any direction will be valid.
