Mishna Berura Summaries

Siman 110 – Tefilla while at work / Tefillas Haderech

  • These days, employers are not makpid on their workers regarding daavening. The standard, therefore, is to allow them to daaven the entire nusach b’zmano, with a minyan like anyone else (and even to be the chazzan if that will not delay the worker more). (ShA 2 – MB 12 – BeH “v’ha’idna”)
  • When your friend leaves you you should not say to him “Laych b’shalom” rather “laych l’shalom”. But when you leave a dead person you should say “Laych b’shalom”. (MB 17)
  • When going on a journey say the Tefillas Haderech in the plural form except for the word “oos’nayni l’chayn…” (ShA 4 – MB 19)
  • Learn Torah on the way. Do not look deeply into a halacha unless you are a passenger. (MB 20)
  • Do not eat your fill before traveling. (MB 20)
  • Take along food. (MB 20)
  • Take along your tallis and tefillin even if you are planning to return the same day. (MB 20)
  • If you are able to be stationary (i.e. stop walking/stop the vehicle) while saying the Tefillas Haderech it’s better. But if you will be worried about the delay, keep moving. (ShA 4 – MB 22,23)
  • It is not necessary to dismount for Tefillas Haderech. (MB 23)
  • One Tefillas Haderech lasts you the whole day even if you stop to relax on the way. It lasts until you decide to stop over for the night. When you continue your journey in the morning, say it again when you are ready to leave – even though you are still in the city. (ShA 5 – MB 26)
  • If you continue your journey before dawn wait until morning to say Tefillas Haderech unless, by then, your journey will be over. (BeH “tzorich”)
  • If you travel through the night without stopping to sleep, say the Tefillas Haderech in the morning but omit the ending-beracha. (MB 26)
  • It is best to fulfil the opinion that Tefillas Haderech should be said s’mucha lachaverta. Therefore eat or drink something in order to say a beracha achrona and then say the tefilla immediately afterwards. (Another option is to go to the bathroom, say Asher Yotzar, and immediately afterwards say Tefillas Haderech.) (ShA 6 – MB 28)
  • If you can’t say the Tefillas Haderech s’mucha lachaverta, you can say it by itself. (MB 28)
  • It is customary to inform great people of your trip and to get a blessing from them. (MB 28)
  • When travelling less than a parsa (4,608km) out of the city do not say the ending-beracha. (ShA 7)
  • Tefillas Haderech should be recited, l’chatchila, once you leave the city (70+ amos from the last building) while still within the first parsa of the journey. If forgotten, it can still be said so long as you haven’t reached within a parsa of your destination for the day. If you remember too close to your destination, say it without the ending-beracha. (ShA 7 – MB 29)
  • Upon entering a bais medrash or even when learning on your own – say a prayer that includes the following:

a: Protect me from mistakes in halacha.

b: You Hashem are the source of knowledge and understanding.

c: Enlighten my eyes to see the wonders in Your Torah.

d: Let me correct any mistake I have made.

When learning in a chabura daaven also:

e: Protect me from being happy about the mistakes of my friends and they shouldn’t be happy about my mistakes.                         (ShA 8 – MB 34,35)


  • Upon exiting the bais medrash (for the day) say a tefilla thanking Hashem for granting you a portion among those of the bais medrash. Apply this even upon completing a day of learning privately.               (ShA 8 – MB 37)
  • These two tefillos are obligatory. However, they do not require standing, facing east, or any bowing. (MB 36)
