Shmoneh Esrei

From Halachipedia

Location

  1. Preferably, one should Daven close to a wall so that there’s nothing interrupting between you and the wall. However, if something is established like a table or closet it isn’t considered an interruption between the person davening and the wall. [1]
  2. If one isn’t unable to stand next to the wall because of the lack of space, one shouldn’t refrain from Davening for this, rather one should close one’s eyes or pray from a siddur so as not to loose concentration. [2]
  3. A bed that’s used for sleeping isn’t considered an interruption between the person davening and the wall, however because some argue on this, one try to strict not to daven in front of a bed used for sleeping if that’s possible. [3]
  4. A object that’s needed for Davening such as a shtender isn’t called an interruption. [4]

Doubt whether one prayed

  1. If one is unsure if one said Shemona Esreh yet, one should pray again with a stipulation of Nedavah, and one doesn’t need to add any new idea in the Shemona Esreh. [5] The stipulation of Nedvah is: If I am obligated to pray, let this prayer fulfill that obligation, if I’m not obligated, let this prayer be a voluntary prayer. [6]

  2. Taz 90:5 write that if there’s not enough space in a room where ten people are Davening, one shouldn’t refrain from Davening rather one should daven and make an effort to have kavanah by closing one’s eyes or looking into the siddur only. Mishna Brurah 90:63 brings this as Halacha.
  3. Mishna Brurah 90:65 writes that a bed used to sleep on is considered established and not an interruption (based on Bet Yosef) however because some (Bach and Taz) argue that it is an interruption, one should try to avoid Davening in front of a bed used for sleeping if it’s possible.
