I have a little story that has come to it's unfortunate end just today, which I think is worthy to share with the CR chevra.
In the past year, I had the z'chus to visit the great R' Chaim Kanievsky to get a brocho. My chavrusa requested that I take a paper with a couple of names to request a refua shelema. I was with a couple people and we all went in separately with our requests. When it got to my turn, I handed him a paper with my requests, and was wished Hatzlocho. I then handed over the second paper that my chavrusa requested I bring for him.
What happened next is startling:
The Rov takes the paper, looks for a second, and suddenly screams out "Hashem Yirachem!!". He said it so loud that people heard from outside the room when the door was closed.I was taken aback and couldn't say anything. It was as if the Rov was predicting horrible news.
I made sure not to relate to my chavrusa what happened at the Rov's house, as on the names he sent with me were one of his relatives, and one of his Mashiach from a previous yeshiva. I wasn't sure which one the Rov made the comment about, so I stayed quiet.
Today, my friend passed around a paper to learn le'ilui nishmas the Mashgiach that passed away yesterday. The unfortunate prediction came true.
I kept the paper until today, and I will keep the paper for a long time, as I feel it signifies the Power of a Gadol.
