What happens when you are moving the knob of the radio? You are tuning it to a particular station. When the frequency of the internal circuitry matches frequency of the station you wish to listen to, it starts to resonate. This resonance enables you to clearly hear the station you wish to. What happened to Najashi RA when Jabir RA
was reciting the Holy Quran to him? The inscription on his soul started resonating with the words of the Holy Quran and he started weeping. The effect the Holy Quran had on his heart made it crystal clear to him that it has the same source as Taurah and Injeel.
