Lit., "whereupon they would have hearts wherewith they might understand, or ears whereby they might hear".
The word for "heart" in Arabic speech imports both the seat of intelligent faculties and understanding as well as the seat of affections and emotions. Those who reject Allah's Message may have their physical eyes and ears, but their hearts are blind and deaf. If their faculties of understanding were active, would they not see the Signs of Allah's Providence and Allah's Wrath in nature around them and in the cities and ruins if they travel intelligently?
