What kind of debate this is.... I'm a doctor and I did my research concerning DNA characterization or DNA profile. Even if there are million or billions of people... everything can be managed and be judged by the DNA results. The DNA profile can be matched with a reference or standard and everything could be made crystal clear either its fake or genuine.
I fully agree with
jennyrock42. There are different protocols for DNA extraction and its possible for DNA extraction even with hairs.
I can see here very strange comments:
DNA research or results are not valid... this is the height of stupidity. If we have different results with DNA profile then this is a foolish thing that a man still believes on Shajra.
For information, if you go for the chemical structure of the DNA and know its properties exactly, you would find out that even after million of years, the DNA remains the same and get preserved.
We must make a demarcation line between logics and emotions. Even in Quran Allah says... "Tafakkroon" "Tadabbaroon" .. Make search and then re-search. People get angry with the scientific results, rather they should think that even if a man dies, his DNA would remain the same. This is the individuality or singleness of each and every person. This shows that every single man has to be answerable for his own deeds before Allah. This is a great miracle.
The issue of fake or genuine shajra... it has nothing to do with "Eiman or Tauheed". We should think with an open mind. Not to be very rational or harsh at any cost. If we have counter-logics we should present before people. If not then we have no right to say Yazeed, or Qadayni... Is this Islam? This is Allah who will judge, not me or you.
