In the above verse, the phrase, ``OF THE QURÄN'' is taken by some of the commentators to imply that, certain verses of the Qurän have the healing qualification, and not all the verses and the whole Book.

      Other commentators have understood that all the verses do have the said curing effect, and in other word, the verse may mean:ِ

      ``We have sent down the Qurän gradually, and any verse or passage that has been revealed, has some sort of a healing effect, and mercy, for the believers.''

      Among the verses of Qurän we find remedies for our mental and spiritual diseases. Some of the verses induce hope in us. Some of them infuse new energy and new life in the believer. Its glad-tidings on account of the life to come, and the promise of God's Mercy and forgiveness, fill our heart with a mysterious happiness.

      It is only the oppressors and the rebels against God's Law, who will suffer loss. This is because the building material of the unbelievers whom Qurän has called them the oppressors; has taken another form, and a second nature, due to their blasphemy, discord, and hypocrisy. They try to put off the light of truth, and cover the facts and realities of life by holding the spirit of rebellion in themselves.

      The physical and spiritual diseases of Man are some how similar, and in connection to one another. Both are fatal, and want a physician to cure. Both kinds might be contagious and may become uncurable.

      Qurän is a healing and reviving prescription for those people who want to fight against their ignorance, pride and vanity, jealously and hypocrisy. Qurän is the remedy and curing medicine for those who are sick in love with the material world and passions, and its allurements.

      A good example to prove the healing effect of Qurän, is to compare the Arabs of the Pagan Era, with those Arabs who, a little later became Muslims. Consider how they overcame and overthrew the supper powers of the time! (Persians and Romans)

      Of course the said prescription can only be effective when it is sincerely followed, and has been put to action.

      If the patient do not use the medicine prescribed by the doctor, he is far from cure.
