With due respect, sir, medical practitioners or health care professionals are not scientists (although they do take basic science courses).  They learn their trade exactly the way a tradesman or a tradeswoman does, first by "supervised learning" (which is called "internship") and later by

practicing (killing and poisoning a few on the way with drug overdoses).  Medical researchers are scientists, who develop disease etymology and cure for the disease (or at least means of prevention).

Secondly, I am afraid, sir, you are betting on the wrong horses: Dr. Jamil, unfortunately, is a "cut and paste man," who neither has any experimental facility nor conducts any research.  The gentleman doesn't even know how one goes about initiating a "hypothesis" and support a theory with reliable and scientifically acceptable self-generated experimental data.  A theory for your information, sir, is generated when a scientist present his/her data in a "peer reviewed" established scientific journal [for example, Nature, London, Proc. of the New York Academy of Science,  Science or Journal of Physics, etc.] and not by citing a cutting from Izvestia, a Russian newspaper.   The calibre of Dr. Jamil's science stinks from here to heavens.

The so-called Indian religious mullah, Mr. Zakir Naik has twisted ideas both about the Koran and the Sunnah.  I have no respect for a Muslim who seeks "God's blessings" upon a Godless assassin Yazid bin Mauwya, and tries to justify it.  Of course, he  (because he memorizes various passages of the Koran --- which is quite common feat with "hafizul Koran") quotes various Koranic passages out of context (followed by Hadiths) to support his arguments to impress those who know very little about both the Koran and the Sunnah.  Ignorant  (even educated one) can be easily impressed.

I can see why we Muslims as an Ummah are back in the abyss of ignorance because of one eyed being kings over us blinds.
