Siman 177

(11.) And he then also warned me greatly to pray for his dear precious child Shlomo Ephraim of blessed memory — for he had the cough illness at that time. And he greatly urged me to multiply prayer for him. And he said: "I know that when I handed the book to the aforementioned men, they would take hold of themselves and overpower those against the child" [meaning the prosecuting forces]. And he also greatly warned the one to whom he handed the book — one of the two aforementioned men — at the time he handed it to him: for G-d's sake that he be careful to pray and beseech much for the aforementioned child. But in our many sins, the prosecution intensified until the aforementioned child passed on in that summer.
