Chofetz Chaim Daily 18 Adar 5:2 Asur to tell people that ploni is weak/not smart etc. because this will damage him socially & financially. 5:3 See sefer for more details. 5:4 Worse to say that ploni isn’t such a scholar; e.g. if he’s a Rabbi, it will damage his spiritual influence and livelihood. If he’s a newlywed, it will embarrass him and his new family.
