Question: How much room exactly do we need for Djawharatul Kamal recitation during the Wazifa?
Recitation of Djawharatu-l-Kamal is subject to conditions. If its conditions are met, then it is obligatory to recite it during the Wazifa. Replacing Djawharatu-l-Kamal by twenty Salatul Fatihi without valid reason invalidates the Wazifa. In the same way, reciting Djawharatu-l-Kamal without fulfilling its conditions invalidates the Wazifa.
Among its conditions :
The place where the Djawharatu-l-Kamal is performed must be pure and large enough to contain at least six people -- do not take into account the physical persons who are present and the furniture, for example: if 5 people and one chair fill entirely a room, we can do the Djawharatu-l-Kamal in this room.
If the place is too narrow, for example, it cannot contain more than two or three people, the Djawharatu-l-Kamal must be replaced by twenty Salat Fatihi.
Another example: if the place is large enough and we are only sure that a parcel of its place that can contain two or three people is pure, and so we do not know if the rest of the room is pure or not, then it is compulsory to extend a pure cloth covering the space required for six people. If it is not possible, then we must replace the 12 Djawharatu-l-Kamal by 20 twenty Salatul Fatihi.
