What can I say when a good friend’s mother has passed away? Is zichrono livrachah enough?
When you refer to your friend’s mother, saying “your mother, zichronah livrachah” (meaning, “of blessed memory”) is ideal. In consoling her, you should seek to console her to the best of your abilities. Also use the expression: Hamakom yenachem otach betoch sha’ar aveilei Zion Yerushalayim.
