LEV381 At times, an additional prohibition is violated, that of cursing with Hashem's Name. Unfortunately, people often speak lashon hara out of anger, and in the heat of the moment, they curse the other person, even with Hashem's name. If he curses with Hashem's Name, in any language, then he transgresses the full-fledged prohibition of לֹא־תְקַלֵּ֣ל חֵרֵ֔שׁ, “Do not curse a deaf person” (Vayikra 19:14). (When the pasuk says not to curse a deaf person, it means even a deaf person; it is certainly forbidden to curse someone who is not deaf, as explained in Shulchan Aruch Choshen Mishpat 27:1.)
