Qadiyanis are overwhelmingly obsessed to hold polemics with the MUSLIMS and every Qadiyani is fully "armed" owning to his peculiar intentions.
On the contray , a common Muslim is almost completely unaware of these issues.
Therefor, prima facie, a Qadiyani apparently gets and upper hand, and this is then extensively propagated.
Every Muslim should study this book with diligence and intrest, no Qadiyani in the wolrd would ever dare to invite him for any argument or a dialogue.
