Order of Non-Wool Tallit and Tefillin
Question
The Shulchan Aruch, Orach Chaim 25 rules you should put a Tallit on before tefillin, this is based on the principle of Tadir, mitzvot which are more common take precedence, generally. However, if one holds that a tallit made of material which is neither wool nor linen is only rabbinically obligated in Tzitzit, then which comes first, the Tallit or tefillin, as tefillin are a biblical law and this view holds that this Tallit is only a rabbinic law.
