Reb Meir Harlig related:

Every year, a set of daled minim was prepared for Rebbetzin Chana, the Rebbe’s mother.

Mrs. Chaya Sarah Weiner lived with the Rebbetzin in her apartment in her later years so that she wouldn’t be alone, and she would also use the Rebbetzin’s lulav and esrog.

A few days after the Rebbetzin’s histalkus on 6 Tishrei 5725, the Rebbe asked for a set to be prepared for Mrs. Weiner.

Before Yom Tov, prior to going to the Ohel, the Rebbe inquired whether it had been done. When a clear answer was not forthcoming, the Rebbe said, “I won’t go to the Ohel until I have been told that the set for Mrs. Weiner has been prepared.”
