<font size=3>There are two Dinim in Shulchan Aruch about wearing a
Yarmulka. First in OC 3:6 it says one should not walk four amos
with a bare head. In 91:3 it says that one may not mention Hashem's
name with a bare head. The Mogen Avrohom says that mentioning
Hashem's name is an issur while walking four amos or even less is a Midas
Chasidus. The Taz disagrees and says that walking four amos is an
issur of "B'Chukoseihem Lo Seileichu".<br><br>
The Sdei Chemed says that based on this, you should not greet a
bareheaded Jew with the greeting "Shalom" since he is likely to
return this same greeting. Since Shalom is one of the names of
Hashem's, it would cause him to be oveir on this Din. </font></body>
