Assalam Alaikum,

Many non muslim ask that why you marry to your cousin sister since they call you "Bhaiya".
In islamic history many mulsim got married with their sisters and brothers when human beings were populated but now a days also we are getting married with our cousins and lot of non muslims say that this is seems to be incorrect in your religion.

So please answer me the so that I can convey the islamic facts about this issue to the unknown people including me.
