Praise be to Allah.
    The traveller is one of those to whom Allaah has granted a 
    concession allowing them to break the fast in Ramadaan. Allaah says 
    (interpretation of the meaning): 
“So whoever of you 
    sights (the crescent on the first night of) the month (of Ramadan i.e. is 
    present at his home), he must observe Sawm (fasts) that month, and whoever 
    is ill or on a journey, the same number [of days which one did not observe 
    Sawm (fasts) must be made up] from other days. Allaah intends for you ease, 
    and He does not want to make things difficult for you”

    [al-Baqarah 2:185]

    It makes no difference whether the journey is difficult or 
    easy. 

    The scholars differed concerning the definition of what makes 
    a person a traveller and thus entitled to the concessions granted to 
    travellers, one of which is that a fasting person may break his fast. 

    The majority of scholars define it in terms of distance, 
    which is approximately 80 kilometers. 

    Others – and this is the view favoured by Shaykh al-Islam Ibn 
    Taymiyah – are of the view that what counts is ‘urf (custom – what is 
    customarily regarded as travel), and not the distance. 

    So whatever people customarily regard as being travel is 
    travel, and comes under the rulings on travel in sharee’ah. 

    Undoubtedly travelling from Amsterdam to Paris is something 
    that people would customarily regard as travel, even if one comes back the 
    same day. 

    Shaykh Ibn ‘Uthaymeen said in al-Sharh al-Mumti’ 
    (4/257) concerning a man who travelled a long distance in a short period: “A 
    short period for a long distance, such as one who travels from al-Qaseem to 
    Jeddah and back in one day – this is called travel, because people prepare 
    themselves for it and they think that they are travelling.” End quote. 

    The distance between al-Qaseem and Jeddah is approximately 
    900 kilometers.  

    Based on this, if a person travels from Amsterdam to Paris 
    and comes back the same day, he is travelling according to both scholarly 
    opinions, whether we base it on the distance or on what is customarily 
    regarded as travel. 

    Is it better for him to fast or not to fast? 

    The answer is: 

    It is better for him to fast unless he finds it difficult, in 
    which case it is better for him not to fast. 

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

    It is better for the traveller to fast, unless he finds it 
    too difficult, in which case he may break his fast. The evidence that it is 
    better for him to fast is as follows: 

    1 – This is what the Messenger  (peace and blessings of 
    Allaah be upon him) did. Abu’l-Darda’ (may Allaah be pleased with him) said: 
    We were with the Prophet  (peace and blessings of Allaah be upon him) on 
    a hot day, such that one of us would lay his hand on his head because it was 
    so hot, and there was no one among us who was fasting except the Messenger 
    of Allaah  (peace and blessings of Allaah be upon him) and ‘Abd-Allaah 
    ibn Rawaahah. Narrated by Muslim. 

    2 – If he fasts it will be easier for him, because making up 
    the fast may be more difficult – in most cases – than doing it at the proper 
    time. That is because if he fasts in Ramadaan he is fasting at the same time 
    as other people, and that will be easier for him. When Allaah enjoined 
    fasting on His slaves, He said (interpretation of the meaning): 
“ Allaah intends for you ease, 
    and He does not want to make things difficult for you”

    [al-Baqarah 2:185]

    3 – If he fasts Ramadaan whilst travelling, he will discharge 
    his duty more quickly, because no one knows what will happen to him after 
    Ramadaan, so fasting will discharge his duty more quickly. 

    There is a fourth benefit, which is that if he fasts in 
    Ramadaan he will have fasted at the best time, which is Ramadaan. 

    But if it is too difficult he should not fast when he is 
    travelling, because the Prophet  (peace and blessings of Allaah be upon 
    him) saw a crowd around a man who was shaded from the sun. He said: “What is 
    this?” They said: “One who is fasting.” He said: “It is not righteousness to 
    fast when travelling.” He said that to one who fasted whilst travelling 
    although it was difficult for him. One day when the Prophet  (peace and 
    blessings of Allaah be upon him) made a stop during a journey, those who 
    were fasting fell down because they were exhausted, whilst those who were 
    not fasting put up the tents and gave water to the travellers and animals. 
    The Prophet  (peace and blessings of Allaah be upon him) said: “Today 
    the reward has gone only to those who are not fasting.” Narrated by Muslim.
