Is it necessary to see the Imam?
Question:
There is a mosque near to us and to the north side of it is a walled piece of land which is attached to the mosque. We would like to make it into a place of prayer for the women to pray in during Ramadhan; is this permissible, bearing in mind the fact that they cannot see the Imam and they can only follow (the Imam) via the loudspeaker?
Answer:
Regarding the correctness of their prayer, there is some disagreement among the scholars, if they cannot see the Imam or those behind him, but can only hear the Takbir; but it is safer for them not to pray on the land described, unless they find a place in the mosque behind the worshipers, or another place where they can see the Imam or some of the worshipers.
