The fatwa of the shaykh Muhammad ibn al Uthaymeen (may Allaah have mercy on him) says that the traveler is allowed the dispensation of shortening and combining his prayers, and of not fasting so long as he is still considered to be a traveler because of the general meaning of the texts. This was also the view of Shaykh al-Islam Ibn Taymiyah before him. But the majority of scholars say that the traveler may only avail himself of the dispensations attached to travel so long as he does not intend to stay for four days or more. This is more on the safe side, and this was the fatwa of Shaykh ‘Abd al-‘Azeez ibn Baaz (may Allaah have mercy on him).
