Hello I have a Yemenite friend who says netillat yadaim blessing and then washes. Where r the sources for this and what is the halachic standing
This is the opinion of the Rambam. Yemenite tradition follows the rulings of the Rambam over Shulchan Aruch.
Rambam Brachos 11:3, Tefillin 4:7, see also Tshuvot Rav Avraham Ben Harambam pg. 122 [Fryman edition]
