Read this part of the book “Iqan” carefully:

      As you observe, the Excellency Baha has said: ”Some atheists have implanted: is it possible for gold to be changed into cupper? Tell, yet. I swear by my Lord that I am knowledgeable about it and I can teach whoever I like… All metals can be changed to each other; but the method is hidden in our book… if people were merited, they could observe the hidden divine sciences.[1]”

     The depth of the Excellency Baha will be clear when he has stated: “if a cupper material is kept out of the reach of humidity, it will turn into gold during 79 years. If some consider the cupper itself as gold, they have been ill due to constipation and haven’t achieved their rank.[2]”

     Anyway, the Baha’is who consider the teaching of the conformity between religion and science and wisdom as their principle must agree with physic and chemistry scientist who says: How is it possible for cupper which is an element lighter than gold to be changed into gold?!!!
