The verse,

I heal him who was born blind, and the leper, and I raise the dead by God’s leave, (2:60)

concerning a miracle of Jesus, upon him be peace, alludes to and encourages the highest level of healing with which the Lord endowed him. It suggests:

It is possible to find cures for even the most chronic ailments. Therefore, O man! O calamity-stricken sons of Adam! Do not despair! Whatever the ailment, its cure is possible. Search for it and you will find it. It is even possible to give a temporary tinge of life to death.

By the verse God Almighty means:

O man! To a servant of Mine who renounced the world for My sake, I gave two gifts, one the remedy for spiritual ailments, the other the cure for physical sicknesses. Dead hearts were quickened through the light of guidance, and ill people who were as though dead found health through his breath and cure. You too may find the cure for all illnesses in My ‘pharmacy’ in nature where I attached to each thing many important purposes. Work and find it! You will certainly find if you seek it!

Thus, this verse marks the final point of medical developments, a point far ahead of the present level, and urges man towards it.
