Greeting People before Davening

From Halachipedia
  1. If one met one’s friend in the market (in a happenstance way) one may greet them by saying "Good morning" but should not say "Shalom". [1]
  2. If this is a powerful person, and one meets him on the way, one can tell him "Shalom" [2].
  3. One may not go to someone’s house to greet them with “Shalom” once the time for Shacharit began. If one met the person on the way, it is preferable not to greet them with “Shalom”. [3]
  4. This prohibition only applies to initiating the greeting, but it is permissible to respond to someone who greeted you. [4]
  5. Once the time for Shacharit comes until one said Brachot HaShachar one may not greet one’s friend with the word Shalom but rather should do so with good morning. [5]
  6. One should not go out of one’s way to greet one’s friend, in the case that one does one should not greet them even with "Good morning", even if one already said Brachot HaShachar. [6]

  1. S”A 89:2 writes that if one meets a friend in the market one may greet them with Shalom and some say that one should greet them with good morning. Mishna Brurah 89:13 writes that we hold like the second opinion.

  3. Gemara Brachot (14a) writes that one should greet someone with Shalom prior to Shacharit. Rashi and Tosfot (14a s.v. BeMashkim) hold that if one accidentally met a friend on the way one may greet them with Shalom. However, the Rashba (14a) quotes the Raavad who holds that even if one does not specifically arrange to meet one should not greet with the word “Shalom”. Shulchan Aruch 89:2 rules like Rashi (as the anonymous first opinion) that if one has not arranged to meet, one may greet a person with "Shalom".
