Malik said, "If the imam stops off on a journey in a town where
jumua is obligatory and he gives a khutba and takes the jumua prayer
for them, then the people of the town and any other people present do
the jumua prayer with him."
Malik said, "If the imam gathers people for prayer while he is travelling in a town where the jumua prayer is not obligatory, then there is no jumua for him, nor for the people of the town, nor for anyone else who joins them for the prayer in congregation, and the people of the town and anyone else who is not travelling should complete the prayer."
Malik added, "A traveller does not have to do jumua "
