Reply To: Where it says that there is a jiyub to put on Tfillin every day?

There is a commandment to say Kries Shma in the morning which requires tefillin as it says to tie it on as a symbolism an os on your hand and head. On Shabbos and Yom Tov since they are a symbolism for themselves, we don’t need to put on tefillin. You should say kries shma in its right time without tefillin (if unable to put on) and re-say it when tefillin is available. We don’t put on tefillin at night.
