Answer: If there are two or more people, they can conduct a congregational prayer. The important requirement here is that the person who is going to lead the prayer (Imam) must fulfill certain conditions.

Answer: Taking part in Friday and congregational prayers of the Ahl-e Sunnat is permissible in areas where Taqiyah (dissimulation) is required. If you are not going to face a problem, you should, as far as possible, prostrate on something upon which Sajda (prostration) is permissible. Prostration on carpets in the case of Taqiyah or out of necessity is permissible and there would be no objection in it. Also, it is obligatory upon you to recite first chapter al-Hamd and the second chapter yourself – with the recitation in a low voice though.

Answer: Praying in congregation (Jama'at) with its conditions is preferable to praying individually. Its preference is stronger in the dawn, sunset and night prayers. A noble hadith says: "A salat [in congregation] behind a learned scholar is like [praying] a thousand cycles; and behind a Qurayshi is like [praying] a hundred cycles."

Answer: It is recommended for women to attend congregational prayers as evidenced by an authentic tradition from the Commander of the Faithful, Ali (AS) that women used to attend congregational prayers but they were ordered to linger their sajda (prostration) because some men were wearing tight garments but there is another authentic tradition which says that a woman's prayer at home is more virtuous than her prayer in a mosque. However, the conclusion that can be drawn from both traditions is that a woman's prayer at a place where she is not seen by non-mahram men (strangers) is more virtuous. If she can perform her prayers in a mosque without being seen by strangers, the prayer in a mosque would be more virtuous in that case.
