As for the second question, there is well known controversy among scholars concerning this issue. The correct opinion is that it is permissible to establish Jumu`ah Prayer with three persons at least if they are residents of a village wherein Jumu`ah is not performed. As for specifying the number of worshippers as forty, twelve, less or more than this in order for Jumu`ah prayer to be established, there is no reliable evidence for this as far as we know. What is obligatory is that it should be performed in congregation by three persons or more. This is the opinion of a group of people of knowledge, which was adopted by Sheikh­ul­Islam Ibn Taymiyyah (may Allah have mercy on him). This is the correct view as stated previously.
