The student, on the other hand, has duties peculiar to him: he must honor the shaykh and not weary him (1); direct others to what he has heard (2); never forgo seeking benefit out of shyness or pride (3); write down everything he hears in full (4); give due care to notation and accuracy; and review what he has memorized (5) so that it becomes firmly rooted in his mind.
Among the important issues (6) is to know (7) the proper age for reception and transmission of ḥadīth. The sounder view is that the age for reception is tied to the child’s ability to discern right from wrong, and this pertains to learning by audition. Hadith scholars customarily bring children to their sessions and record their attendance for them, but such attendance (8) requires the explicit permission of the dictating teacher. As for the age at which a person pursues study on his own (9), the correct view is that he must first be qualified for it.
Reception by a non-Muslim is also valid provided he transmits the material after embracing Islam, and, with even greater reason (10), the same applies to an openly sinful Muslim once he has repented and his integrity has been established (11).
