Question: [Sunday, 27th Kisleiv 5781]
After I lit my candles outside on Erev Shabbos a wind came and blew them out within ½ hour from after sunset. Did I fulfill my obligation?
Initially, one may not light the candles in a windy area that can potentially extinguish the candle, and if one did so then he only fulfills his obligation if it remained lit for ½ hour at least after sunset, otherwise it is subject to a debate in Poskim. If, however, one lit it in a safe area and then an unexpected wind came and extinguished it, then one nonetheless fulfills his obligation.
