Al-Husayn ibn Said, from Uthman ibn Isa, from Samaah, who said: I (narrator) asked Imam عليه السلام about ‘fasting while travelling.’ Imam عليه السلام said: “There is no fasting while travelling. Some people fasted during the time of the Messenger of Allah سبحانه وتعالى, Allah’s سبحانه وتعالى blessings be upon him and his family, so the Prophet صلى الله عليه وعلى آله وسلم named them the ‘disobedient ones’. Thus there is no fasting while travelling except the three days which Allah سبحانه وتعالى, Mighty and Majestic, mentioned regarding the Hajj.”
