Question: When travelling with others, is it best for everyone to recite tefillas haderech, or can we listen to one person recite it and say amen ? Answer: The Shulchan Aruch (OC 124:1) writes that the chazan repeats the amida ( chazaras hashatz ) on behalf of those that do not know how to daven. However, the Mishna Berura (124:1) writes that this only applies to one who is not able to easily daven by themselves. One who is able to daven properly cannot fulfil their obligation simply by listening to the chazan’s repetition. The Gemara ( Berachos 29b) refers to tefillas haderech as a tefilla.

Therefore, he writes that one who is cooking would be allowed to rinse meat, even though inevitably their hands will get wet. Nonetheless, R’ Pesach Eliyahu Falk (Machazeh Eliyahu 1:87) demonstrates that one must avoid getting one’s hands wet as much as possible. One cannot bathe their children unless it is absolutely necessary. This applies even though the restriction against bathing does not apply to children. He quotes the Beis Yosef (OC 616) who explains that unlike feeding one’s children when one does not benefit oneself, by bathing one’s children, one’s own hands get wet. Therefore, one must not wash any dishes that were used to feed one’s children o...
