and it further indicates that, if a trustworthy person informs him on the basis of independent reasoning, he does not act upon that person’s statement. For example, a group is travelling, none of whom knows the direction of the qiblah or is able to determine it through independent reasoning, but one of them knows it through such reasoning.
