well thats ignorant behavior from thos Qataris or whatever nationality behave like that .,
some people take islam by name and looks not implementation.

In Islam : قال الرسول عليه الصلاة والسلام "كلنا لآدم، وآدم من تراب، فلا فرق بين عربي وأعجمي إلا بالتقوى" وكذلك "لا فرق بين أبيض وأسود إلا بالتقوى"}

Translation : Said the Prophetmohamed, peace be upon him, "We're all to Adam, and Adam from the dust, there is no difference between Arab and non arab only piety" and "no difference between black and white only piety")
