Is it permissible for me to adopt the view of one who permitted the combining of prayers for a traveler as long as he is outside his original country, and is it permissible to act upon the sayings of scholars other than the majority of scholars?

A Muslim must follow the evidence from the Qur’an and Sunnah in matters where the evidence is known to him, and he may emulate whomever he believes to have sound ijtihad (independent reasoning) in matters he does not know. He is not obligated to follow a specific madhhab (school of thought) or person. There is no excuse for one who follows an opinion knowing that the evidence is contrary to it. The obligation is to adopt from the sayings of scholars that which reassures the heart, without seeking out concessions. It is permissible to adopt the قول (saying/opinion) of a trustworthy scholar even if it differs from the majority, as long as it does not reach the extent of seeking out concessions.
