Muwatta Malik Book 5, Hadith 15
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 "
Yahya related to me from Malik that he had asked Ibn Shihab about the word of Allah, the Majestic, the Mighty, "O you who accept, when the call is made for the prayer on the day of jumua, make haste to the remembrance of Allah."(Sura 62 ayat 9). Ibn Shihab said, ''Umar ibn al-Khattab used to recite, 'When the call is made for the prayer on the day of jumua, go to the remembrance of Allah.' "
Malik said, "Making haste in the Book of Allah is only deed and action. Allah the Blessed, the Exalted, says 'and when he turns away, he acts in the land' (Sura 2 ayat 205), and He, the Exalted, said, 'and as for the one who comes to you acting with fear' (Sura 80 ayat 8), and He said, 'then he turned his back, and acted' (Sura 79 ayat 22),and He said, 'Your deeds are diverse' " (Sura 92 ayat 4). Malik said, "Thus making haste which Allah mentions in His Book is not running on the feet or exertion. It only means deed and actions."
Yahya related to me from Malik from Abu'z Zinad from al-Araj from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, mentioned the day of jumua and said, "There is a time in it when Allah gives to a muslim slave standing in prayer whatever he asks for," and the Messenger of Allah, may Allah bless him and grant him peace, indicated with his hand how small it was.
