As per the title, does one earn any reward/s'char for the attempt (or even just the intent) to perform a mitzvah?
This evening, we all piled out of shul to say Kiddush Levana only to find that the sky was too cloudy, but we were all ready and interested in doing the mitzvah. If it ends up that, because of the weather, we cannot perform the mitzvah this month, do we receive any reward for our intent or trying to perform it?
