“The proof of the pudding is in the eating”, as we say in England. It is the sheer efficacy of these words – their saving and transforming power – that convinces me of the Divine origin of the Qur’an.
For example, the Qur’an claims that by praying the five daily prayers we will be kept away from indecency and evil acts:
‘Recite that which has been revealed to you of the Book and keep up prayer; surely prayer keeps (one) away from indecency [obscenity/immorality] and evil, and certainly the remembrance of Allah is the greatest, and Allah knows what you do.’
I have found this to be absolutely true. Not just with external acts but in my inmost being.
Also the Qur’an promises to be a healing and a mercy to believers. This reality is harder to put into words, but the Book subtly affects the heart, softening it, giving it spiritual nourishment, orienting it to what really matters in life:
We send down (stage by stage) in the Qur’an that which is a healing and a mercy to those who believe: to the unjust it causes nothing but loss after loss.
Is this just my subjective experience? Well yes – and no! Anyone can experience this for themselves from whatever their background. And this it does, and has always done, as the history of our Faith proves.
