The word Darabah has a number of meanings in Arabic, and I mentioned the various meanings (not sure if it was all recorded). As for the Miswak point, this is based on a hadith that we have that states it. To be objective in any topic, I have to present the various opinions and viewpoints, and so I was presenting the viewpoint of some scholars that the hitting (when the conditions are fulfilled) must be light and with a Miswaak. But I was not advocating for this view and claiming that it’s the correct view. What I understand from the Miswak hadith is that it’s a method to break the ice.
One of the possibilities of the verse is that ضرب comes from the word اضراب which means to go on strike. Going on strike means to stop spending on them, to separate from them, etc… So this is one possibility scholars have stated (and it is supported by a hadith).
Another possibility is that ضرب comes from the word ضرب في الارض which means to travel. But most scholars have rejected this possibility
