a story of a Gadol who came to Eretz Yisroel
he was known to not leave his house on Shabbos
when finally asked to explain he said that the first Shabbos in E’Y he saw someone smoking and he fainted.
the questioner stopped him and said, oh so thats why you dont leave the house on Shabbos?
he said no
its because the next Shabbos he again saw someone smoking…..and he didnt faint
