Benefit:
Whenever the need is felt, these acts should be performed; however, if there is a delay, it should not exceed forty days, otherwise one will be sinful.
It should not be assumed that cleanliness should not be maintained before forty days.

14. Commentary:
➊ Day and night are inseparable from each other; therefore, whether one says "day" or "night," it makes no difference.
➋ Forty days is the maximum limit; otherwise, whenever there is a need—meaning if one feels disgust or filth and dirt begin to accumulate—cleanliness may be maintained, whether it concerns hair or nails.
