Is the view of one who says that it is obligatory for sick people and travellers to break the fast and that their fast is not valid correct?
Question

                What is your opinion on the view of one who says that sick people and travellers are obliged to break the fast and make it up later on, and it is not permissible for them to fast, because Allah, may He be exalted, said (interpretation of the meaning): “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” [al-Baqarah 2:185], so what is obligatory for them is to make up the fast, and this means that they should not fast?.
Praise be to Allah.
      A concession is granted to the sick person for whom it is 
      difficult to fast, and for the traveller, to break the fast during the 
      month of Ramadan, because Allah, may He be exalted, said (interpretation 
      of the meaning): “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” [al-Baqarah 2:185]. 

    But if they fast, then their fast is valid, because of the 
    hadeeth of ‘Aa’ishah (may Allah be pleased with her) according to which 
    Hamzah ibn ‘Amr al-Aslami (may Allah be pleased with him) said to the 
    Prophet (blessings and peace of Allah be upon him): Can I fast whilst 
    travelling? And he was a man who fasted a great deal. The Prophet (blessings 
    and peace of Allah be upon him) said: “If you wish, fast; and if you wish, 
    do not fast.” Narrated by the group. 

    But if they fear for their lives if they fast, then it is 
    obligatory to break the fast, because of the hadeeth of Jaabir (may Allah be 
    pleased with him) who said: The Messenger of Allah (blessings and peace of 
    Allah be upon him) was on a journey and he saw a crowd of people and a man 
    being shaded (from the sun).  He said: “What is this?” They said: He is 
    fasting. He said: “It is not part of piety to fast whilst travelling.” 

    The concession allowing the traveller not to fast is also 
    general in application, because of the hadeeth of Hamzah ibn ‘Umar 
    al-Aslami, in which he said: “O Messenger of Allah, I find that I have the 
    strength to fast, is there anything wrong with that?” He said: “It is a 
    concession from Allah, may He be exalted, so whoever avails himself of it 
    has done well, and however wants to fast, there is nothing wrong with that.” 
    Narrated by Muslim. 

    With regard to the verse in Soorat al-Baqarah, the confusion 
    about its apparent meaning may be dispelled, in sha Allah, once you know 
    that in this verse there is something which is implied, which is “break the 
    fast” i.e., whoever among you is sick or on a journey and breaks the fast, 
    then “the same number [of days which one did not observe Sawm (fasts) 
    must be made up] from other days”. The scholars have explained this and 
    there are many other similar examples in the Qur’aan and Sunnah and the 
    Arabic language. 

    And Allah is the source of strength; may Allah send blessings 
    and peace upon our Prophet Muhammad and his family and companions. End
