Rabbi Avrohom Baruch Zachariash teaches the halachas of Chanukah with the Mishnah Berurah (O.C. 671): Why should we be careful regarding the mitzvah of Chanukah, but not necessarily other mitzvos; You don’t get sued if you don’t have money; Getting dressed to save a life; Is it more important to be Shomer Shabbos or Fast on Yom Kippur; Should you light wax candles, pre-made olive oil, or set up the oil and wicks from scratch; plus lots more!
