Al-riḥla li-l-ḥadīth is travel undertaken to acquire and investigate transmitted reports.
A sensible method begins with the scholars of one's own locality. After making proper use of the available teachers and their narrations, the student travels to seek chains and knowledge not accessible locally.
The benefit is not simply a larger total of reports. Travel can provide alternative routes, comparisons among teachers, elevated chains and evidence relevant to hidden mistakes.
Increasing the number of teachers is valuable only when accompanied by genuine reception, verification and precision.
