Can Jumuah be performed in Arafah and can one perform Jumuah in small groups in the Mina camps?

Answer

Under no circumstances is Jumuah allowed in Arafah. Jumuah is allowed in Mina on condition the Khalifah or his appointed deputy performs the Jumuah. This is not found in current times, hence Jumuah is not valid in Mina. Performing Jumuah in small congregations in tents or even as a big jamaat in Mina is not valid. Zuhr Salaat has to be performed.
