It seems the great kabbalist R. Yitzhak Kaduri has been having serious health problems lately. However, he has nothing to fear because the Lubavitcher Rebbe promised him that he would live to see the coming of mashi'ah. Arutz Sheva reported on September 14th of last year:
During a visit in 1990 with the late Lubavitcher Rebbe, Rabbi Menachem Mendel Schneerson (of blessed memory), Rabbi Kaduri was told by the Rebbe that he would live to see the coming of the Mashiach.link
UPDATE: It seems that this post went over a lot of readers' heads. My point was simply not to take such predictions/prayers/blessings as absolute prophecy.
