The final letter written by the late Rav Yosef Sholom Eliyashiv, who passed away today, before he was hospitalized, was a haskamah for a sefer written by a Chabad avreich, Rabbi Eliyahu Tzvi Yakubovitch, a graduate of the main branch of Tomchei Tmimim.
When he visited Rav Eliyashiv, the young avreich was accompanied by his grandfather, Rabbi Shimon Yakubovitch, who is also Rav Eliyashiv’s nephew.
The sefer, Oholei Tzvi, is currently being printed. It contains chiddushim on Baba Kama, including haskamos from Gedolei Yisrael of all backgrounds, led by Rav Eliyashiv, and many others.
“At the end of the sefer, I included a kuntress from my great-grandfather Rabbi Aharon Yakubovitch, and Rav Eliyashiv wrote me a letter about this, and this was actually the last letter he ever wrote. In addition, he wrote a haskamah for the actual book,” Rabbi Yakubovitch reported.
In the past, Rav Eliyashiv also wrote haskamos for Rabbi Yakubovitch’s earlier works.(SOURCE & PHOTOS: OL.ORG.IL)
