Laws Governing [Preparations for] the Onset of Shabbos, 2 Seifim: It is a mitzvah to wash Rema: one's whole body. If it is not possible he should wash (Tur) his face, hands and legs with warm water on Erev Shabbat. It is a mitzvah to wash one’s head and trim one’s nails every Friday. Rema: If one’s hair [has grown] too long, it is a mitzvah for him to cut it. And when one trims one's nails one should not grab hold of them in order. One should begin trimming the nails of his left hand with [those of] the kami­tzah, (i.e., the fourth finger, the one next to the pinky). On the right hand, [one should start] with the index finger, the second finger, the one next to the thumb. Thus, a memory cue for the order is בדאג"ה (2, 4, 1, 3, 5) on the right hand and דבהג"א (4, 2, 5, 3, 1) on the left. (Avudraham in the Sefer HaMussar)
