Pls provide the related Hadiths.
Cutting of the nails is Sunnat. The Mustahabb method is to start from the
right index finger to the right small finger then the right thumb.
Thereafter, the left hand from the small finger to the thumb. Cutting of the
toe nails will be from the small left toe to the small right toe.
Cutting of the nails should not be left for more than 40 nights although it
is preferable to cut them once a week. (Mirqaat vol.2 pg.45)
