First Section – the Positive Commandments
36. It is a positive commandment to take the four species on Succos
As it says in Vayikra (Leviticus) 23:40, "Take for yourself on the first day a fruit of the tree of elegant beauty, branches of palm trees, boughs of thick leaved trees, and willows of the brook." These are: one lulav, one esrog, three haddasim, and two aravah. A person is required to take them like they grow and when they are lifted, he has fulfilled his obligation. All day a person is allowed to take the species to shake them. According to the Sages, a person should take all four species everyday of Succos, except Shabbos. The Sages forbade taking them on Shabbos even if the first day of Succos is Shabbos because a person might carry them four amos (about six feet) in a public domain [which is breaking a Shabbos law]. All of the four species are required to be able to fulfill the mitzvah - if one is missing, the mitzvah is not fulfilled. If the species are borrowed, it is unacceptable on the first day of Succos but acceptable on all other days. According to the Sages, a child old enough to know how to shake the species is required to, in order to teach him how to perform the mitzvah.
This applies in all places and at all times for men but not for women.
