Halacha Yomi: January 22 2019 (greeting before davening)

Greeting –  Beginning from Alos Hashachar (some say this begins at Neitz), one should not go to someone else’s door to say שלום. This includes to not even say good morning. However, if one is going to someone else’s house for some other reason, it is permitted to greet him, but only with a good morning, and not to say שלום. However,it is better not to even say good morning.
