We need to get over the diseases of nationalism, tribalism, different ethnicities, different languages that may lead to differences amongst us, when in reality they should be a reason for our strength as an Ummah. This variety that we have, the different backgrounds that we have, the different ethnicities that we have, the different languages that we speak, should be a source of strength for us and not a source of weakness.
Brothers and sisters, if we go back to Qur'an we'll find the answers but the problem is that we follow our whims, we follow our desires, we follow what we believe to be right and wrong, not what Allah tells us to be right and wrong.
~ Imam Anwar Al Awlaki (Rahimahullah)
