The majority of scholars agree on this hadith:
And he (may Allah have mercy on him) said in Sharh Saheeh Muslim
(3/149): It is mustahabb to start with the hands before the feet, and
to start with the forefinger of the right hand, then the middle
finger, then the ring finger, then the pinkie finger, then the thumbs,
then to move to the left hand and start with the pinkie finger then
the ring finger, until all the fingers are done, then to move to the
right foot and start with the smallest toe on the right foot and end
with the smallest toe on the left foot. And Allah knows best.
