The gaon Rabbi Nachum Kornbisser, rosh yeshiva of the Chiddushei HaRim yeshiva related’ the following:
During the month of Shevat 5730 (January-February, 1970) when letters were being sold for the Torah scroll of Moshiach, I was staying with the Beis Yisroel at his home in Kfar Shmaryahu. Some Chabad shluchim came to visit the Admur in connection with the matter of the Torah scroll. The Admur later told me: ‘I inscribed a letter, and I also gave them money. I heard a rumor that there is someone who opposes the Rebbe’s declaration that this Torah scroll can bring the Redemption; I am completely incapable of fathoming this opposition.’
At that time, there was also a rumor that a certain individual described the matter of the Torah scroll as idolatry, G-d forbid. In reaction to this, the Beis Yisroel told me: “I find it very hard to believe that so-and-so said this; but if I were to find out that he did indeed say it, I would no longer wish to meet with him. I once had a visitor who called Breslov “idolatry”; after that, I was no longer prepared to meet with him. You should know that the Lubavitcher is an awesome person [a moradiker mentch], leader of Israel.’ I heard many times from the Admur’s holy mouth that the Lubavitcher Rebbe is the greatest leader of our generation”
