What was the commandment prescribed by Prophet Muhammad (saw) regarding the time limit for grooming activities such as clipping the moustache, cutting the nails, plucking hair under the armpits, and shaving the pubes?
 Anas reported:                      A time limit has been prescribed for us for clipping the moustache, cutting the nails, plucking hair under the armpits, shaving the pubes, that it should not be neglected far more than forty nights.
