[1] The Ahádith of this chapter show that it is permissible for one to observe Saum (fast) or to break his Saum (fast) while travelling. But it is recommended for a healthy strong person to observe Saum (fast), whereas a weak or sick person is recommended not to observe Saum (fast). The saying of the Prophet (ﷺ) "It is not from AI-Birr (righteousness) to observe Saum (fast) on a journey," is applicable to a particular case, i.e. when one is so weak or sick that observing Saum (fast) would harm him. In such case one has to break his Saum (fast), for Allah does not like His devotees to harm themselves needlessly.
