Question :

Prayer in the Outdoor
Question :

Sometimes, when I am travelling or commuting, I have to pray on the outdoors somewhere by the street, otherwise the prayer time will end. Is this permissible, and is it permissible to keep our shoes on when we pray?

Answer :

Praying in the Same Room
Question :

If a man and a woman are praying in the same room, how far apart they must be from each other.

Answer :

It is permissible for the man and woman to pray next to each other, although it is disliked. Such dislike can be avoided when the position of the man is ahead of the woman, in such a way that when she prostrates her forehead would be adjacent to his knees. It is better that the man's position is ahead of that of the woman's by a distance of a step.

Prostrating on the Rock
Question :

Why do we pray on the rock? And is it prohibited to pray on carpet like Sunnis without a rock?

Answer :

Prayer is not valid on the carpet since prostration - based on the jurisprudence of the Ahlulbait (peace be upon them) - must be on natural earth like soil, stones, rocks and similar materials, or on what grows on earth provided that it is not consumed for food or worn as clothing. It is narrated - in both Sunni and Shia books of traditions - that the Prophet (peace be upon him and his holy progeny) said: "Earth is made for me as a place of prostration and a purifying agent". Some Sunni books of narrations state that the Prophet (peace be upon him and his progeny) used to have a piece of cloth in which he put soil in it and he opened it and prostrated on the soil.

Prostrating on Paper Towel
Question :

Can we do the prostration of prayers on a paper towel?

Answer :

If the paper towel is made of a substance upon which prostration is not correct, like cotton, then it is not permissible to prostrate on it. If it is made of a substance upon which prostration is correct, like wood, then it is permissible to prostrate on it. If the individual doubts or does not know the source of the towel then it is impermissible to prostrate on it.

Prostrating on Agate
Question :

While praying, is it permissible to perform prostration on the agate (aqeeq) of the ring you are wearing in case a turbah is not available?

Prostration of the Prayers
Question :

I do not always prostrate in prayers on earth or something which grows from the earth. Will my prayer be void?

Answer :

Your prayer is valid only when you prostrate on something other than earth or what grows from it in the following cases:
(i) If you did so because you did not know that the material you prostrated on is not one on which prostration is required to be performed upon.
(ii) If you did so because you did not know that it is a condition in the prayer that you must prostrate on earth and the material that grows from it.
(iii) If you forget and did not pay attention until after performing the prostration.
(iv) If you did this out of fear - taqiyyah.
Otherwise the prayer is void and should be repeated.

Turbah
Question :

I notice that after using a Turbah for a long time, it becomes slightly to (eventually) very dark at the part that would make contact with my forehead, likely due to bodily oils and sweat over a long period of time. Is there a point when I can no longer pray on the turbah because the colour of it has changed significantly or can I always pray on it regardless?

Answer :

If this darkness on the surface of the Turbah does not become a barrier that prevents the forehead from coming in direct contact with the turbah, then it is permissible to prostrate on it.

Prostration in the Dark
Question :

Is it permissible to offer the prayer in the dark when one cannot see what he is prostrating upon?

Answer :

It is permissible to pray in the dark if prostration is done on what is permissible to prostrate upon. If prostration is not done so, then the prayer should be repeated based on compulsory precaution.
