Question
Shalom aleichem Rabbi Lauffer. Thank you for answering my last question. The Mishnah Berurah rules that in order to fulfill the mitzvah of lulav with someone else's lulav, and the owner of the lulav doesn't know that one has to own the lulav in order to fulfill the mitzvah the first two days of Sukkos, the owner must give it to you as a gift on condition that you return it. Once you are given the lulav as a gift on this condition, when you return it to the original owner, in order to put it back in the owner's reshus, do you also have to give it to him as a gift, as a gift on condition that it be returned, or do you just have to give it to him stam, without saying it is a gift. Thanks a lot.

Major parts of the regular Friday evening services are: Kabbalat Shabbat, Shema, Shabbat Maariv Amidah, Kiddush for Friday evening.

Please explain why we omit Kabbalat Shabbat if Friday evening is also Yom Tov (Festival).
