'Promise To Name Him Chaim'

When R' Aharon of Belz first came to Yerushalayim he stayed at the home of a Lubavitcher Chossid named R' Zalman Ashkenazi. Two buildings away lived a talmid chochom named R' Feivel who was raised in a very misnagdishe environment and was close to chasidim like I am close to Japanese fishermen. R' Feivel and his wife had been married for twenty years and had not been blessed with a child. On the yahrtzeit of the Ohr Hachaim Hakadosh, Rav Chaim Ben Attar [ט"ו תמוז], R' Feivel's wife dreamt that she saw him. She woke up and related her dream to her husband who didn't attribute much significance to it. She then told one of her friends who was chasidic and her friend suggested that she go to the tzadik R' Aharon two buildings away and tell him of her dream.

She did so and R' Aharon told her to go that very day to his grave on Har Hazeisim and to say all of sefer tehillim and then daven for a child. She should promise the Ohr Hachaim to name the son she bears "Chaim" in memory of the tzadik.

EXACTLY one year later on the yahrtzeit of the Ohr Hachaim, R' Feivel's wife gave birth to her one and only son, who was named ..... "Chaim".
