Minimum number required for Jumu’ah prayer

In regard Jumu'ah prayers, what is the minimum number of people
required to pray in congregation behind the imam. I have heard
different opinions ion reference to this such as some brothers have
told me that a minimum of 40 people are required while others have
said 2.Adifferent source has also said that only 2 people can
constitute to a congregation for jumu'ah prayers. Can you please
clarify this question for me.
Praise be to Allaah.
The Standing Committee for Issuing Fatwas was asked the following question:
What is the number of men required for Jumu'ah prayer to be valid?
Some people say that it is not valid with less than forty men, and if
there is one less than that, they should pray Zuhr.
Answer: Establishing Jumu'ah prayers is obligatory (waajib) upon the
Muslims in their villages on Fridays, and it is necessary for there to
be a jamaa'ah (congregation) in order for the Jumu'ah prayer to be
valid. There is no proven evidence (daleel)which states that a
specific number is required; for the prayer to be valid it is
sufficient for there to be three or more people. It is not permissible
for a person who is obliged to pray Jumu'ah to pray Zuhr in its place
when there are less than forty people present – according to the
correct scholarly view. And Allaah is the source of strength. May
Allaah bless our Prophet Muhammad and his family and companions, and
grant them peace.
