Acquisition of knowledge is incumbent on every Muslim. Accordingly, the tradition intends to state that at whatever stage of knowledge one May be, he should strive to make further advance. The Prophet means that acquisition of knowledge is obligatory for all Muslims, scholars as well as ignorant men, beginners as well as learned scholars. Whatever stage of knowledge man may attain, he is still like a child entering into adulthood i.e. he should learn things which were not obligatory for him earlier.
