Everyone I ask has a different interpretation of Surah nisa 4:34. Some say it means light beating but the verse clearly says to hit without any indication of the strike being light. I don’t understand and I can’t find anyone to answer me.

The verses must be clarified through the Hadith of the m’asoom, which indicate that it should be a light tap. Rather, it likely should never reach even that stage. Please read this exchange:
