Take regular baths; brush teeth twice a day; trim mustache; shave pubic hairs; pluck armpit hairs; clip nails .

This hadith teaches us the importance of taking care of our personal hygiene and grooming regularly. It was narrated by Anas bin Malik that we were given a time limit with regard to trimming the mustache, shaving the pubic hairs, plucking the armpit hairs and clipping the nails. We were not to leave that for more than forty days. This hadith emphasizes on taking care of our physical appearance in order to maintain good health as well as good looks. Taking regular baths, brushing teeth twice a day, trimming mustache, shaving pubic hairs, plucking armpit hairs and clipping nails are all part of maintaining good hygiene which should be done within 40 days at least once in order to stay healthy and look presentable at all times.
