With the starting of tractate Moed Katan, R' Chaim Kanievsky said that it is known in the name of the Chasam Sofer that there is a concern in learning Moed Katan because of the fact they you are learning the halachos of mourning. Therefore the Chasam Sofer said that a person should give charity before learning this tractate.- published in the Yated Neman via Jewish Worker
R' Kanievsky added that certainly someone who gives charity to "Kupat Hair" will be saved from any pain and anguish and has nothing to worry about.
As always, the names of all donors will be passed on to R' Kanievsky for a blessing
Its a good thing I don't believe in the superstition and also follow Rabbis who think learning Moed Katan is important.
And to quote the Rav when people asked used to ask him for a bracha (blessing) :
What are you an apple?Also it is shameless to say donate to my charity and no harm will come to you. Now if that only worked.
