The Conditions of the Friday Prayer:

1-       The setting in of Dhuhr prayer time.

2-       The two speeches must be heard by the forty men.

3-       The prayer has to have been performed in congregation by the forty inhabitants.

4-       Another Jumu^ah Prayer must not be performed simultaneously in the same town. If the opening Allahu akbar of one prayer preceded that of another, the former would be valid and the latter would be invalid. However, if it was hard for the people to meet in one place, then in as many places as was needed, the Prayers, both earlier and later, would be valid.
