Halakhah for Sanhedrin 131:31

From the laws of the commandment is that which they, may their memory be blessed, said (Shevuot 35a) that it is forbidden to curse in any way. But nonetheless, he is not lashed unless he cursed with a name of one of the names [of God], such as Y-ah, Sha-dai, E-loah and similar to them, or with any appellation of one of the appellations [of God], such as Compassionate, Jealous and similar to them. And he is liable in any language that he curses with a name or appellation, as the names that the gentiles call the Holy One, blessed be He, are among the appellations (even though they are in their languages). And [also] that which they said (Shevuot 36a) that even one who curses himself is lashed, as it is stated (Deuteronomy 4:9), "But you shall guard yourself and guard your soul much." And also that [which they said] in Mekhilta (see Sanhedrin 66a), "'You shall not curse the deaf' - [it is speaking] about the wretched among men." And they also said there (Mekhilta d'Rabbi Yismael 22:27) that when the verse (Exodus 22:27) states, "a chieftain (nassi) among your people, you shall not maledict, etc.," it implies both a chieftain and a judge. What [then] do we learn by saying, "[Judges] shall you not curse"? To impose liability for this one in itself and for that one in itself. From here they said, "One may speak one thing and be liable for four things. (How so?) If the son of a chieftain curses his father, he is liable on account of chieftain, on account of father, on account of judge, and on account of 'among your people you shall not maledict'" (see Tur, Choshen Mishpat 26).
