He is travelling and the time for Jumu’ah has come; should he pray it as Zuhr and shorten it and join it to ‘Asr?
Question

                A man is travelling and on the way the time for Jumu’ah prayer will come. Should he pray it as Zuhr and shorten it and join it to ‘Asr, or should he pray it without joining it?.
Praise be to Allah.
    Jumu’ah prayer is waived for the traveller, so he should pray 
    Zuhr, shortening it to two rak’ahs, and he may join it with ‘Asr at the time 
    of the earlier or later prayer, according to what he needs to do. But it is 
    better not to join it unless he needs to do so, if it will be difficult for 
    him to perform each prayer at its own time. 

    Shaykh Ibn ‘Uthaymeen (may Allah have mercy on him)  said: 

    The traveller does not have to pray Jumu’ah, and the evidence 
    for that is the fact that during his journeys, the Prophet (blessings and 
    peace of Allah be upon him) did not pray Jumu’ah, even though he had many 
    people with him; rather he would pray Zuhr and shorten it. End quote. 

    Al-Sharh al-Mumti’ (5/10) 

    Shaykh al-Islam Ibn Taymiyah (may Allah have mercy on him) 
    was asked: 

    Is it better to join two prayers whilst travelling or to 
    shorten prayers? 

    He replied: 

    Offering each prayer at its proper time is better, if there 
    is no need to join prayers. Usually when the Prophet (blessings and peace of 
    Allah be upon him) was travelling, he would offer prayers at the proper 
    times, and he only joined prayers on a few occasions. End quote. 

    Majma’ al-Fataawa, 24/19. 

    He also said (may Allah have mercy on him): 

    This shows that joining prayers is not part of the Sunnah of 
    travelling, unlike shortening prayers. Rather it should only be done when 
    there is a need for it, whether one is travelling or not. End quote. 

    Majma’ al-Fataawa, 24/64 

    Shaykh Ibn Baaz (may Allah have mercy on him) said: 

    The one for whom Allah has prescribed shortening of prayers, 
    namely the traveller, is permitted to join prayers but the two concessions 
    do not necessarily go together. He may shorten the prayers without joining 
    them, and not joining them is better if the traveller has arrived at his 
    destination and is no longer on the road, as the Prophet (blessings and 
    peace of Allah be upon him) did in Mina during the Farewell Pilgrimage; he 
    shortened the prayers but did not join them. But he both joined and 
    shortened prayers during the campaign to Tabook, which indicates that this 
    (concession) is prescribed to make things easy when there is a need for 
    that. And he (blessings and peace of Allah be upon him) used to shorten and 
    join prayers if he was on the road and was not staying in the place. End 
    quote. 

    Majma’ Fataawa Ibn Baaz, 12/289 

    Usually when the traveller is on the road he needs to join 
    the prayers, because that is easier for him, so that he will not have to 
    make a further stop in order to pray, which may be difficult for him and delay his journey. 

    Based on that, it is permissible for you to pray Zuhr as two rak’ahs and join ‘Asr to it, at the time of the earlier or later prayer, according to what is easier for you. 

    And Allah knows best.
