Mustahab places for offering prayers

902. In Islam, great emphasis is laid on offering prayers in a Masjid. Masjid Al – Haraam is superior to all the Masjids, and after it, the order of priority is as follows:

• Masjid An – Nabi (peace be upon Him) (in Medina)
• Masjid Kufa (in Kufa)
• Masjid Bayt Al – Maqdas (in Jerusalem)

The ninth condition: The place where the person offering prayer places his forehead, should not be lower or higher than the place where he places his knees and feet’s thumbs by four fingers (put together). The detail of this issue will be given in the rulings of Sajdah (prostration).

The eighth condition: If the place of the person offering Namaz is Najis, it should not be wet in such a way that its wetness reaches his body or clothes. If the place where he places his forehead is Najis but dry, even then his prayer will be invalid. As per recommended precaution, the place of the person offering Namaz should not be Najis at all.  

The seventh condition: The place where a person places his forehead while in Sajdah, should not be higher or lower than a span of four fingers, when compared to

the place of thighs or toes of his feet. The details of this rule will be given in the rules relating to Sajdah.

898. For a Na-Mahram man and woman to be at a place, where there is a possibility of falling into sin is Haraam. As a recommended precaution, one must avoid praying at such places.

The sixth condition: As an obligatory precaution, women should stand behind men while praying. At least, her place of Sajdah should be in line with his thighs, when in Sajdah.

896. If a woman stands in line with man, or in front of him in Namaz, and both of them begin together, they should repeat their prayers. And the same applies if one of them starts earlier than the other.

The fifth condition: If the place where one wishes to pray is Najis, it should not be so wet that its moisture would reach the body or the dress of the person praying. But, if the place where one places one's forehead while performing Sajdah, is Najis, the prayers will be void, even if that place is dry. And the recommended precaution is that the place where one offers prayers should not be Najis at all.

The fourth condition: The ceiling of the place where one prays should not be so low, that one may not be able to stand erect, nor should the place be so small, that there may be no room for performing Ruku’ or Sajdah.

894. If a person is forced to offer prayers at a place where it is not at all possible to stand, he will pray while sitting. And if it is not possible to perform Ruku’ and Sajdah, he should perform them by head signs.

The third condition: A person should offer prayers at a place where he sees the possibility of completing the prayers. To pray at a place where one cannot complete the prayers, because of strong winds, or heavy rains or a teeming crowd, will render Namaz void, even if one somehow manages to finish the prayers.

892. If a person offers prayers at a place where it is forbidden to stay, like, under a roof which is about to collapse, his prayers are in order, though he will have committed a sin.

889. The second condition: The place for prayers should not have such a vigorous movement which would make normal standing, Ruku’ or Sajdah impossible. In fact, as an obligatory precaution, it should not prevent the body from being at ease.
But if one is forced to pray at such places, due to shortage of time, or any other reason, like in a car, on a ship or on train, then one should try to remain still, and to maintain the direction of Qibla, as much as possible. And if the vehicles move away from the direction, he should return to Qibla.
